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.

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 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

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

A pencil holder wearing a puffer jacket: quilted panels all round, with a zip, a collar and sleeves running up the sides. It holds pens, pencils, markers, brushes or small tools, and it is sturdy enough to be knocked about a desk. About two hours of printing, and the quilted panels take filament colours well - solid winter colours, pastels, or something loud.

Design by Sitsero

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

Design by Morganja

A printable reading ruler with an integrated bookmark pointer. The pointer holds your line while you read and marks your place when the book closes - pick the length that suits your book.

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

Design by Morganja

A japandi vase with a rifted surface: a faceted body that catches the light along its ridges and narrows to the rim.

Design by DueMakers

An angled, ribbed plant pot for a windowsill, with a drip tray that stands it clear of its own water. The pot tapers up from a 45-degree base and drops into a tray with a hollow reservoir, so what drains out sits below the base instead of wicking back up into the soil, and the tray lifts off to empty. The floor has a 2.5 mm centre hole, a ring of six, and a ring of twelve at the outer edge. Forty-eight round bead ribs run up the angle and on to the rim, so the pot has something to grip and looks alive in daylight. Three sizes, each one as wide as it is tall: 2.5"x2.5", 3.25"x3.25" and 5"x5". It prints as two pieces, no supports and no assembly, in PLA - which is happy on an indoor sill, while a window that bakes in direct sun or a spot outside wants PETG. The last picture is a render of the printable model; the others are photographs of the printed pot.

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 low-poly vase built from big flat facets that twist as they rise, so light catches every plane differently. 5.5" across its widest and 3.9" tall, printed in one piece.

Design by Harry

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

A guide that keeps a garden hose off the flowers: the hose runs through the roller and the stake holds it where you want it, so dragging it round a corner stops flattening the bed. 4.7" tall, printed as a body and a stake. Shown as a render, not a photo.

Design by Tulmuz

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 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

A round indoor pot with a pleated, fabric-like skirt, standing on its own matching base so it can be moved without leaving a ring on the shelf. Two pieces, both printed in the same colour, 4.6" wide and 3" tall together. Shown as a render, not a photo.

Design by NordicCreativa

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

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

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). Shown as a render of the printable model, not a photograph.

Design by Matthew

A hanging books-read counter: a sign with a row of numbers that slide into it, so the count can be moved along as the year goes. It is two plates - the sign with one of each number, and a second sign with the numbers again so the count can pass ten - and either can be bought on its own. Shown as a render, not a photo.

Design by ZHeights

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 T-rex that holds your page: the dinosaur stands on the spine of the book with its legs either side, and the tail curls over the top. It prints flat in one piece, 3.6" tall. Shown as a render, not a photo.

Design by UncleFlappy

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 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 square indoor planter with ruched, fabric-like sides and a clean flat rim, so it reads as a cloth-wrapped pot until you pick it up. It prints in PLA with a drainage hole in the base, and it is 4.7" wide by 3.9" tall. Shown as a render, not a photo.

Design by Dossi

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.

Design by Abz

A paw that rides on top of a straw: the straw passes through the middle of it, the paw sits above the lid, and the raised pad and four toes catch the light as the cup moves. It is made for the 10 mm Stanley straws, 3.5" tall by 1.6" across, and it prints in one piece. Shown as a render, not a photo.

Design by Morganja

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 reading guide that frames one line at a time so the page cannot swim: 5.1" x 1.4", 1.4 mm thick, light enough to leave in a book. Kept for kids learning to read, and for anyone whose attention slides down a full page. Shown as a render of the printable model, not a photograph.

Design by fgiancarelli

A modular hydroponic tower printed as twelve parts: a base, the column that stacks, five growing cups and the plates that close the sides. The column is 220 mm across and 128 mm tall, each cup 55 mm. The modules come apart, so a tower can be built one section at a time and taken down again. Shown as a render of the printable model, not a photograph.

Design by user_139533078

A three-part seed germinator - base, insert and lid - 4.5" x 5.5" and 20 mm deep, printed in whatever colour you pick. Shown as a render of the printable model, not a photograph.

Design by 3dmonios

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. Designed by AndreUser and printed under Creative Commons Attribution 4.0 (CC BY 4.0). The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A mosquito trap that uses a jar you already have: a funnel that drops into a mason jar's mouth, so a jar of water and a spoon of sugar becomes a trap. The cone lets a mosquito in and the jar's own walls keep it there. Three funnels come off the plate, 76 mm across and 47 mm tall, for the jar sizes the designer covered - standard jam jars among them. Designed by IanFoulds, a remix of the Mosquito Trap by Urasxman, and printed under Creative Commons Attribution 4.0 (CC BY 4.0). Shown as a render of the printable model, not a photograph.

Design by IanFoulds

A short sword bookmark with its own sheath: the blade marks your page and the scabbard clips back over it. 5.7" long, printed flat, the two pieces together weighing about 8 g. Shown as a render of the printable model, not a photograph.
