A pair of arrow earrings, each with a coiled shaft, a small loop at the tip for the hook and a heart-shaped flight. They print flat and weigh well under a gram for the pair, so they want hooks or studs fitted afterwards. Each is 2.1" by 0.7". The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own.

A Spartan helmet in profile, crest and all, 2.2" tall, with a loop at the top so it hangs as a pendant or swings on a keyring. It prints flat in one piece, which keeps the crest and the cheek guard crisp.

Design by OrangeSs

A low-poly Labrador, faceted like cut stone, standing with its head up: the low-poly build keeps it light enough to print and lets it catch the light along the facets. Two sizes - the big one at 4.7" tall and a pup at 2.4" - each printed in one piece.

Design by CreaitivityStudio

Two spirals in one print: an outer shell that twists one way and a core that twists the other, turning past each other as you fiddle. Printed in a single colour it reads as one tapering cone; give the shell and the core a colour each and the two spirals separate in the eye as they turn, which is what the designer's own pictures show. The profile that prints it is 0.2 mm layers, 3 walls, 15 per cent gyroid infill, PLA, no supports, standing upright exactly as supplied.

Design by NerdHerder

An impossible passthrough built as a pyramid: the parts pass through one another and no amount of turning lets them go. 2.8" tall, about 21 g of plastic.

Design by BeninManc

An impossible passthrough shaped like an hourglass: two halves that turn through each other and stay locked together. 2.8" tall, about 24 g of plastic.

Design by BeninManc

A hard hat that goes on a keyring - the dome, the brim and the little ridge down the middle, printed in one piece with a hole through the top. 1.5" across, and it works as a key tag or a desk charm.

Design by astavr

A gyro fidget spinner: three curved rings interlock around a centre post and whirl as one, so it prints in a single piece with no bearings and no assembly - just flick it and go. The rings are loose in their track out of the printer, which is the part that takes a few tries to get right and the reason this one gets measured before it ships.

A one-piece beard comb with rounded teeth that glide through without scraping. Small enough to live in a jacket pocket, and it prints without supports. The solid band above the teeth can carry a name, cut into the surface rather than raised, because a comb lives in a pocket and raised letters are the first thing to wear off: type the name while you are adding it to the cart, up to 12 characters, +$5. A personalized comb is cut to order, so it is paid online rather than reserved for cash at pickup. Leave it blank and it comes exactly as the photos show it.

A crowned lion head with a loop at the top, about four inches tall - a pendant, a bag charm or a wall ornament, with the mane and crown cut deep enough to hold a highlight. One piece. The picture is a render of the printable model, not a photograph of a finished print.

Design by digidihey

A 2 mm PLA cake stencil, 6 x 4 inches, with Happy Birthday and three balloons cut right through. The lettering is a stencil face, so the middles of the a, p, B, R and D stay attached to the plaque instead of falling out. Lay it on a sheet of parchment over the cake, dust with cocoa or icing sugar, and lift it away. Four or more come at the bulk rate. The picture is a render of the printable model, not a photograph; real photos go up once the first one is printed.

A hexagonal tube cut into one continuous spiral, so it springs and flexes in the hand and the turns of the helix roll past each other under a thumb. It prints as a single piece and needs no assembly, and it stands 2.8" tall by 1.3" across. Shown as a render, not a photo.

Design by NerdHerder

A frog that jumps: press its back and it springs off the table, and the pond bowl catches it. Pick the frog on its own or the bowl with it - the bowl is 5" across, and three frogs fit on one plate if you want a set. Shown as a render, not a photo.

Design by Niski

A ruler that folds: nineteen 160 mm segments that hinge end to end, plus the two end caps, so it measures a room and then folds down to a pocket. The full set is 19 segments; the smaller option is the same design at 70 per cent, which is the one for a desk drawer. Shown as a render, not a photo.

Design by PenguinPrototypes

Mark the shark as a keychain or as a necklace charm - the same shark in two fittings, one with a ring hole and one sized for a chain. It prints flat with no supports, about 2.4" long. Shown as a render, not a photo.

Design by dominator334

A desk caddy printed in one piece: a raised back that stands a phone at a reading angle, a round well for pens, and a square tray for a watch, keys or a card, with a slot for a charging cable to pass through. It is 7.1" wide by 3.5" deep. Shown as a render, not a photo.

Design by Maker76

Four Jeep charms, each a different model cut in relief and each with a hole at the top for a keyring or a chain. Pick the one you want - they print flat with no supports and measure about 2.4" by 2.4". Shown as a render, not a photo.

Design by dominator334

The classic folded awareness ribbon with a keyring loop at the top, printed flat so the fold reads cleanly on both faces. It is 2.5" long by 1.4" wide and prints in whatever colour you choose. Shown as a render, not a photo.

Design by Miss3DP

A planetary gear set printed in place: six small gears mesh between a sun gear and a toothed ring, so turning any one of them turns all the rest. It is 2.5" across and prints as a single piece with nothing to snap together. Shown as a render, not a photo.

Design by HurtTree

Five heart shapes, each layered front to back so the colours read as depth: black sits at the back as the outline and the two layers in front are yours to choose, so one colour is the simplest and three makes it pop. Pick the shape you want - each is about 1.6" by 1.5", with a loop for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A tall vase with a drop falling through its wall, and the tray that holds it: the designer made it for a single stem or a bundle of dried grass, and the tray catches whatever you drop in it, which is where the mindfulness comes in. Printed as two pieces - the vase and its holder - so you can use them together as an arrangement or keep the tray on a desk for rings, keys and incense. Standing 24 cm, it wants a shelf with headroom or the middle of a table. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DueMakers

Eight sports-ball charms, each with the ball's own surface cut into it - soccer pentagons, a golf ball's dimples, a basketball's seams - so they read as the real thing at charm size. Pick the one you want: every ball has a hole for a keyring or a chain, prints flat with no supports, and measures about 1.7" by 2". Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

A layered volleyball charm: the ball's panels are cut as separate raised layers, so the seams read as depth rather than a printed line. It is 1.6" by 1.4", has a hole at the top for a ring or a chain, and prints flat in one piece. Shown as a render, not a photo.

Design by CoisinhasdaManu

A little cauldron with a lid full of bubbles, sized to sit over a battery tea light: the light comes up through the bubbles and the whole thing glows. It prints in two parts, the cauldron and its top, so the top can be a different colour from the pot - the designer printed the tops in plain white and let the tea light do the colour. About 70 to 77 mm tall once the two parts are together. Battery tea light only, never a real flame. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DJH665

Twenty-six dog charms, each cut with a different dog in relief so it reads at a glance on a keyring or a necklace - the designer's three sets, in one listing. Pick the dog you want: every one has a hole at the top for the ring or the chain, prints flat with no supports, and measures about 1.4" by 2.4". Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

An inner cone passes right through an outer one and neither of them comes apart - that is the whole trick, and it prints as a single piece. Roll it in your hands and the two bodies slide past each other, which is the part that keeps fingers busy. Printed in two colours the cones separate in the eye and the pass-through reads as impossible; printed in one it looks like a solid cone until it moves. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A stackable glasses stand: a fin that the cradles slide onto, so the tower grows to whatever height the collection needs. The cradles come in three widths - 67, 77 and 87 mm - and each holds one pair nose-down by the bridge, which suits slim readers and deep sunglass frames alike. The plate prints a whole tower's worth of parts, 167 by 199 mm laid out as the designer arranges it.

A pair of open heart outlines, each about 1.9" by 1.6" and barely over a gram, with a small hole at the top for the ear wire. They print flat, so the outline stays crisp and there is nothing to finish beyond fitting the hooks. The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render, not a photo.

Design by C4UStudio

A vase with a wave running up its wall - a single spiralling surface, so the ridges catch the light differently as you walk past it. 180 mm tall, and shaped for dried flowers, pampas, feathers, or for nothing at all in a bare corner. It wants a dry arrangement rather than water. Print it in a silk or a matte filament and the waves do the rest of the work. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DueMakers

Three round pet pendants struck like coins, each with a loop at the top for a chain or a keyring and each about 1.7" by 2". The set is all three, printed flat so the faces come out crisp. Shown as a render, not a photo.

Design by dominator334

A modular glasses stand: a round 143 mm base with a spindle, a post that carries two long arms, and a cradle that stacks on the spindle, so two pairs or a shelf-full can be kept upright and out of the way. The arms take frames by the bridge and the base is heavy enough not to tip when one pair comes off.

A phone stand that folds out of a keychain: the plate swings up and the phone leans back on it, and folded away it hangs on your keys. Shown as a render, not a photo.

Design by musielovsky

A graduation cap and gown on a keyring: the mortarboard tilted over the gown, with a class year or a name across the front on the version the designer included for it. It hangs flat and reads clearly from a distance, which is what a keepsake for a graduate wants to do. Printed as one tag with the layered faces so the cap, the gown and the lettering each read separately. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Cardboard Junkie

The Thinker, sitting on a plinth with his chin on his fist and a pair of glasses resting across his knee: 101 by 141 mm and 114 mm tall, printed in one piece as a desk glasses holder. The pose is what does the work - a pair sits in the crook of the arm and the knee, so it is always where it was put.

A keyring that opens without a metal split ring, printed as one piece with nothing to assemble. The flat band is broken once, and across that break the two ends lap through the ring's own thickness - the socket keeps the lower half, the near end the upper, with a quarter of a millimetre of air between them - so the finished ring reads as one band with a hairline in it rather than two pieces butted together. What holds it shut is the gate's own end, narrowed to a tongue: the band's inner and outer edges step down either side of it, and the tongue carries a rounded bump underneath that sits in a seat cut into the socket. Flex the ring apart and the bump rides up its own rounded side, which is a detent and not friction; let go and it drops back in. The tongue is relieved with a round hole at its root, because that is where it bends when you press it up to open the ring. Flex it, thread your keys on, squeeze it shut. The picture is a render of the printable model - real photographs of the print go up once the first batch comes off the printer.

One little ghost, three sizes of it: Small is 35 mm tall, Medium 45 mm and Large 64 mm, so a shelf can gather a few rather than carry a loner. Each prints as a rounded little spectre with a friendly face and no supports. Every ghost is its own object on the plate, so no multi-colour printer is needed - print them in different colours and they arrive as a set. The small one disappears into a bowl by the door; the large still fits in a hand. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Amanda Roos

A fidget spinner small enough to live in a pocket: one piece, no bearings, no axle to glue, printed in place so the two halves and their weights come off the plate ready to spin. It is a 15-minute print in the designer's own profile, which is why it makes a good giveaway or market-stock item. Printed in a silk filament the spinning face catches the light. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DragonFusion3D

A turtle small enough to sit on a shelf edge: the shell is modelled with its own scutes and the head, tail and legs are all there, so it reads as a real turtle rather than a toy one. 2.3" long and printed in one piece. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Type1Printing

A hinged box for rings and earrings, 150 by 83 by 20 mm closed: a tray with compartments, a lid that shuts on printed hinges, and two pins that press in to hold the hinge line - four printed parts, no screws, no supports. Small enough for a wash bag and rigid enough to keep its shape. A remix of "Parametric hinged small parts box" by Billiam on Printables, which is CC BY 4.0, and designed by Ivan Chamberlain under Creative Commons Attribution 4.0 (CC BY 4.0) - both are credited. Shown as a render of the printable model, not a photograph.

Two strands twisted around each other into a pen stand: a double helix about 22 cm tall on a 14 cm square base, printed in one piece with nothing to assemble. Pens drop into the gaps between the rungs and lean out along the twist, so a handful of them fan apart instead of clumping together in a cup - and the base is wide enough that a full stand does not tip. Empty, it is a desk ornament rather than a mug with pens in it, which is most of what a pen holder does all day. Printed in PLA at a 0.2 mm layer, about 34 g of plastic.

A ribbon of open spirals, 60 mm long and 25 mm across, printed upright so the turns come off the plate as clean as they look - nothing to sand between them. One earring fills the plate, so a pair is printed twice. Designed by Mike Olszak and printed under Creative Commons Attribution 4.0 (CC BY 4.0). The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render of the printable model, not a photograph.

Two filigree horse heads, 45 mm by 28 mm and 2.5 mm thick, cut into openwork so they stay light enough to wear all day - about a gram and a half of plastic each. Printed exactly as the designer published them, under Creative Commons Attribution-NoDerivatives 4.0 (CC BY-ND 4.0), designed by C4UStudio. The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render of the printable model, not a photograph.

Two sharpened pencils, 42 mm long and 11 mm across, with the point cut so the graphite reads as a separate tip - about 0.2 g of plastic each, which is light enough to forget they are on. Printed exactly as the designer published them, under Creative Commons Attribution-NoDerivatives 4.0 (CC BY-ND 4.0), designed by Tinker Together. The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render of the printable model, not a photograph.

Eight citrus halves on one plate - orange, lime and lemon - each a 35 mm slice with a hole for a hook, so the set is four pairs or a bowl of citrus to rearrange. Printed flat in PLA with no supports and no colour changes: the segments are geometry, not paint. Designed by jdicerchio and printed under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0); the parts are sold unaltered and this listing is offered under the same licence.

A V-plow that clamps over the front of a clog: two mirrored blades, 118 mm long and 58 mm high, one for each shoe, that push snow aside as you walk. Shown as a render of the printable model, not a photograph.

Design by OVERTUREFilament

An impossible passthrough wound as a spiral: the helical parts turn through each other and hold, printed in one piece. 2.8" tall, about 29 g of plastic. The picture is a render of the printable model - real photographs of the print go up once the first one is made.
