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 one-piece toy bow with a springy arrow that launches when you pull it back. Prints as a single piece with no assembly - ready to play with straight off the plate.

A snake printed in one piece with its body jointed along the whole of its length, so it coils and straightens as you play with it and holds whatever shape you leave it in. The scales run along its back and give it something to grip with. The designer prints it at 0.16 mm layers or finer at 100% scale, which is what keeps the joints free - print it coarser and it will come out stiff.

A dragon that prints in one piece with every plate of its body already jointed, so it coils and straightens straight off the bed - no supports, no assembly, and no loose parts. The spikes run the length of its back and read as armour when it is posed on a shelf. Three sizes: Small is 116 mm nose to tail, Medium is 140 mm and fits an A1 mini, and Large is 223 mm - the one that needs a full-size bed. The designer asks that anyone selling prints credit them and link the model page, which this listing does.

A star that opens and closes as you spin it: a print-in-place kinetic fidget with no assembly and no supports, so it comes off the plate ready to twist. Spinning it expands the arms from a closed cone into an open fan and back, which is the part that keeps hands busy, and it looks good parked on a desk either way. Best in a silk or colour-changing filament, which is what the designer recommends.

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

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 tiny dragon printed as a chain of flexing segments, detailed all down its back and small enough to sit in two fingers. 3.0" long and only a few grams of plastic, printed in one piece.

Design by CrissyCat

A slug that ripples: the body is a chain of segments under a soft brim, so it flows through your fingers and settles into a curl. About 3.0" curled, printed in one piece with no supports. Enlarged and remixed by yusuffles from matveymoo's "Curled up Friendly Slug", and sold under the same share-alike licence.

Design by yusuffles

A monster printed as a chain of flexing segments - horns, a ridge of spines down its back and a tail that curls - so it stands up, slumps and wriggles. 3.9" tall, printed in one piece with no supports, in one colour or three.

Design by TinkerLink

A lucky toad, printed in one piece with no supports, about 1.9" across and 2" tall with its little belly. Four come at the bulk rate.

Design by Ake Studio

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 crocodile printed as a chain of flexing segments - ridged back, four stubby legs and a tail that swings - so it wriggles and curls in your hand. 4.0" long, printed in one piece.

Design by ThePrintDrawer

A cube of eight hinged blocks that folds in on itself: twist it one way and it turns inside out, fold it the other and it closes back into a cube, which is the whole trick and the reason one stays on a desk. It prints as a single piece with its hinges already in place, in two sizes, and needs no supports or assembly.

Design by Print3DFamily

An articulated dragonfly: the body and each wing are cut into flat segments joined by print-in-place hinges, so it flexes in the hand and settles back flat when you set it down. It prints as one piece with no supports, 4" across by 2.7".

Design by Tybob24

A starfish printed as a chain of flexing segments, with five arms that trail and curl so it drapes over your hand. 4.5" across, printed in one piece with no supports.

Design by mieldeprot

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.

A bow that clips onto a straw: the straw runs through the middle and the bow sits above the lid. Shown as a render, not a photo.

Design by Morganja

A tiny dino for a keyring, all of an inch tall, printed flat in one piece. Shown as a render, not a photo.

Design by SG3D

A six-can holder that spins: six runners hold the cans and the base turns, and it uses very little filament for its size. Four pieces. Shown as a render, not a photo.

Design by JEP0405

Wet gloves dry upside down on six tapered, vented posts, over a 4x10 inch floor vent. A glove's cuff slides over a post so warm air from the register goes up through the post and through the glove, drying the inside as well as the out - which is the part that stays wet. The tray is a colander: a lip catches a dribble of water, and a grid of drain holes lets the air up and the water down, and each post drains through its own cup. Bottles and cups fit the posts just as the old stand's did. Sized to sit inside a 4 by 10 inch register, printed in one piece with no supports and nothing to assemble. The photo is a render of the printable model - real photos of the print go up once the first batch comes off the printer.

A dog's head that sits on top of a straw, ears up and nose forward. Shown as a render, not a photo.

Design by Morganja

A fold-over bag clip in one piece, with nothing to assemble: two slim bars on a round hinge, and a hook at the far end that shuts them. Roll the bag's neck over, slide it in side-on between the bars, and press the hook home - the knob at the end of the curl rides over the upper bar's tip and drops into the groove cut behind it, so the clip is held shut by the hook and not by the moulding. Flex the curl back off the tip and it opens again. The hinge is a disc with a hole through it, so the clip hangs on a keyring or a cup hook when it is not on a bag. It prints flat as a single piece with no supports, and PLA holds fine while PETG survives the dishwasher and takes more flexing. The picture is a render of the printable model - real photographs of the print go up once the first batch comes off the printer.

A Jeep grille that rides on top of a straw, seven slots and all. Shown as a render, not a photo.

Design by Morganja

A ghost bookmark: a flat spectre that hooks over the page, thin enough not to splay the spine. There are seven of them in the file, each a slightly different ghost, so pick the one you want - about 1.2" by 4" and printed flat. Shown as a render, not a photo.

Design by PrintcessJacqueline3DDesigns

A bag peg that works like a clothes peg: two arms on a printed pin, so the ends you squeeze and the jaws are on opposite sides of the pivot, and squeezing opens the jaws. A disc on the upper arm turns inside a socket on the lower one, printed in place with a quarter of a millimetre of air round it - press the peg open and you can feel the pin move. Behind it one strip sweeps round and back to the other arm as a scroll you can see through, and that scroll is the spring: it closes the jaws and it is what you feel working when you squeeze. The mouth is a square-wave channel cut through both jaws at once, so the two sets of teeth come from the same cut and interlock - every tooth of one jaw stands in the hollow of the other - and along the outside of each arm, where a thumb goes, a row of sawteeth bites into the silhouette so the peg does not slip in your hand. It prints flat as one piece, no supports, nothing to assemble. PLA holds fine; PETG survives the dishwasher and takes more flexing. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

An eight-legged octopus printed in one piece with its legs already articulated: no supports, no assembly, and it wriggles the moment it comes off the plate. Small enough for a desk or a pocket, and the designer's own profile runs it at 0.16 mm layers, two walls and 8% infill. It takes a two-colour silk filament especially well, which is how the designer's sample is printed. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Halloween tokens that flip and slide: a disc in a frame that turns over in the hand and clicks through a stop, in five designs from a small 2.6" ghost to a wide 3.4" one. Pick the token you want - each prints in one piece with the disc already in its frame. Shown as a render, not a photo.

Design by Toddy's Trinkets

A small articulated dragon: body and tail cut into segments joined by print-in-place hinges, so it curls through your fingers. Shown as a render, not a photo.

Design by BashStudio3D

A heart that sits on top of a straw, wide and low, catching the light as the cup moves. Shown as a render, not a photo.

Design by Morganja

A chef's hat charm with a banded brim, tall enough to read at a glance on a keyring. Shown as a render, not a photo.

Design by Tim

Two clickers that look like lunch: a bao bun with its pleats, and half an avocado with the stone still in. Each is two printed halves that snap together over a switch, so the whole thing is the button. Pick the one you want - about 1.8" across. Shown as a render, not a photo.

Design by iNkosi3D

Hide and seek, fifty times over: fifty numbered ducks, each with its own number cut into it, and a case to hide them in. Buy the fifty ducks on their own, or the case on its own - the case is 5.7" by 3.8" and holds the lot. Shown as a render, not a photo.

Design by TuscaroraTech

Take-away clickers: a burger, a box of fries and a drink cup, each printed as two halves that snap together over a switch, so the whole thing is the button. Pick the one you want - about 1.5" across - or four of any mix come at the bulk rate. Shown as a render, not a photo.

Design by iNkosi3D

Christmas cone fidgets: a spiral cone that runs down through your fingers, and a Santa hat built the same way with its own spiral inside the brim. Pick the one you want - both print as a single piece and stand about 2.8" tall. Shown as a render, not a photo.

Design by Nerdherder

A print-in-place bag clip: the hinge prints shut and then works, so there are no pins and nothing to assemble. 3.2" long, 1.2" wide. Shown as a render of the printable model, not a photograph.

Design by printerforge

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 jeweller's display in one print: a smooth-shouldered bust form for necklaces, a hand for rings and bracelets, both on one base, plus the collar that finishes the neck. 244 mm tall and 233 mm wide - a shop-window piece rather than a bedside one - printed in the parts its designer drew, with a support blocker in the file so the overhangs print without a forest of supports.

A small desk novelty in two parts, 2.5" x 2.6" x 0.8", printed as one plate. Shown as a render of the printable model, not a photograph.

Design by LoboCNC

A set of fifteen Archimedean solids - the truncated and snub forms of the five platonic shapes - each 24 to 33 mm across and printed as one plate. A desk set for a maths classroom or a geometry shelf. Shown as a render of the printable model, not a photograph.

Design by mikan

The 2 to 9 times tables on one flat plate, 5" x 3.6" and 1.6 mm thick - a card that lives in a pencil case rather than on a screen. Shown as a render of the printable model, not a photograph.

A shark in articulated segments, 110 mm from nose to tail, printed in one piece with the joints already free - it swims through the fingers and lies flat in a pocket. Printed exactly as its designer published it, under Creative Commons Attribution-NoDerivatives 4.0 (CC BY-ND 4.0), designed by goatbuster. Shown as a render of the printable model, not a photograph.

A volcano model 5.9" across and 3.1" tall, printed as one piece - a desk piece, or the model for a school project on volcanoes. Shown as a render of the printable model, not a photograph.

Design by euro100xx

A faceted tree on a weighted base, 173 mm tall: rings slide onto the branches, necklaces hang from them, and the low-poly planes catch the light instead of looking like a coat rack. Two pieces, no supports, and the base is wide enough that it does not tip when one branch is loaded. Designed by Beenox and printed under Creative Commons Attribution 4.0 (CC BY 4.0). Shown as a render of the printable model, not a photograph.

A dart-shaped glider printed as one piece: 24 cm nose to tail, 15.8 cm across the wings, 12 mm at its thickest, and about 7 g of plastic. It prints flat, so the whole plane lifts off the plate as one object with nothing to glue together - and being flat it takes a minute or two of plastic rather than a flight. A desk toy that looks like folded paper and will not crease, soak up a puddle or blow off a table. Designed by By_Menen and released into the public domain (CC0 1.0). The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A dinosaur cut into interlocking jigsaw pieces and sold as the whole set: twelve chunky pieces, printed flat in PLA, that push together into the animal and come apart again. Two editions, cut differently from the same artwork - Adult and Kid, with the Kid edition's tabs cut larger for smaller hands. Both print as a set with no supports and nothing to glue, and the loose pieces store as the shape they make. The Adult set is about 322 g of plastic and the Kid set about 352 g, so each one is a multi-plate print rather than an afternoon.

A set of gear examples for teaching - the gears and the pins that hold them, printed as one plate, each gear 80 mm across. Shown as a render of the printable model, not a photograph.

Design by osamutake

A jitterbug mechanism: a foldable polyhedron in print-in-place segments that flips inside out when you squeeze it. One is about 1.8" x 1.6", and printed as one piece there is nothing to assemble. Sold as one jitterbug - the plate in the picture prints four. Shown as a render of the printable model, not a photograph.
