A bowl for rinsing rice: the water swirls through the grain and pours off the side while the rice stays put, so you stop losing half of it down the sink. Two sizes - 6.9" across and a smaller 4.8" - each printed in one piece, with the drain holes and the pouring lip part of the bowl.

Design by ValeraPerinski

Four dinosaur cookie cutters with matching stamp inserts - press the stamp for the details, cut the outline, bake. Each cutter is about 3" across, and the set is four different animals.

Design by Merilno3D

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.

Design by TinkerTogether

A plump bee that clips onto the top of a straw, wings raised and its stripes cut deep enough to read across a table. It suits the 10 mm Stanley straws, is 1.6" by 1.5", and prints in one piece with no supports.

Design by Morganja

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 clip-on egg separator: crack an egg into the channel and the white runs through while the yolk stays put. 3.6" long, printed in one piece, and it sits on the rim of a cup or a bowl.

Design by user_4069524941

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 Jeep grille that rides on top of a straw, seven slots and all.

Design by Morganja

A dog's head that sits on top of a straw, ears up and nose forward.

Design by Morganja

A lid that snaps onto a standard can and seals it up again between sips, and doubles as an opener when you slip it over the tab and tilt. It is the wider, support-free version, and it fits both the slim and the fat cans the designer built it around - European 202 cans, so if yours is a different can it is worth a quick measure. Light sanding on the slots is the only finishing it asks for.

Design by MakerShed

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 corgi that keeps the bread shut: the body is the clip, the ears are the handle and it sits on the bag like a peg. 5.4" long, printed in place in one piece. Shown as a render, not a photo.

Design by Burak19891

Three holders that keep bottles lying down in the fridge instead of rolling out of the door - each cradles one bottle on its side and stacks with the others. The plate prints three, and each is about 9.4" long. Shown as a render, not a photo.

Design by RossMacAllan

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 smiley you can click: the face is the button, and it presses in and springs back with a sound. 3.2" across, printed in one piece with no AMS and no supports. Shown as a render, not a photo.

Design by AmandaRoos

A bag clip shaped like a cat, with a spring jaw that holds a chip bag or a coffee pouch shut. 1.6" across, printed in place in one piece - the hinge comes off the plate already working. Shown as a render, not a photo.

Design by Muuurt

A cupcake you can click: the frosting is the button, and it presses down with a proper click and springs back. Two sizes - 1.2" across for a keyring, 1.8" for a desk - each printed in one piece. Shown as a render, not a photo.

Design by MeltedMoose

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 pair of lips that sits on top of a straw: the straw passes through the middle and the lips ride above the lid, catching the light as the cup moves. It suits the 10 mm Stanley straws, is 3.9" tall by 2.2" across, and prints in one piece. Shown as a render, not a photo.

Design by Morganja

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 Christmas cookie stamp and its matching cutter: press the stamp into the dough and the outline cuts clean around it, so the icing has a line to follow. 3.1" across, printed as two pieces - stamp and cutter. Shown as a render, not a photo.

Design by P2T

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

A glasses rack that lives on the wall: six cradles in a row on one 210 mm plate, 22 mm deep, so six pairs hang out of the way of a counter or a bedside table. It prints as one piece with nothing to assemble, and the arms take wire or plastic frames by the bridge. Designed by Matthew and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

Design by Matthew

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.

Design by What3d

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.

Design by Badger Sound Forge

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.

Design by Rockthered

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.
