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 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 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
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.

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
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 hexagonal fidget that prints flat in a few minutes and clicks between your fingers - no supports, no assembly, no settings to tune. 2.0" across. Shown as a render, not a photo.
Design by LangHjornArt
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 phone stand with a woodgrain surface that all but disappears behind the phone, so what you see is the screen standing on the desk rather than the stand holding it. A deep groove with a lipped front edge takes a phone upright for video calls or on its side for standBy and night-clock mode, and it fits anything from a small handset up to a Pro Max. Printed in PLA at 0.2 mm layers, 15% infill, no supports. It is designed for a wood-fill filament, which gives it the grain it is named for, though any matte colour prints just as well. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

A clicker keychain with four buttons that press and click, printed in place so nothing needs assembling. Shown as a render, not a photo.
Design by Print3DFamilyFidgets
Two bands that print as one piece: the finned outer ring's ridge sits in the inner band's groove, so it is locked on but free to spin, with no bearings and nothing to assemble. The groove is a BALL RACE - a circular channel, with the ridge as the same circle held 0.4 mm off it - so the surfaces the two parts face each other across are vertical, which is what lets it print in place and still turn. The ring is 27 mm across and stands 7 mm, and the fins are trapezoids: wide where they join the sleeve, narrow at the tip, so nothing on it is a blade waiting to be knocked. It comes in three sizes, 16.5 mm (US 6), 18.2 mm (US 8) and 19.8 mm (US 10) across the finger hole, all at the same price, and the download is a 3MF with a plate for each, so you can print whichever fits - or all three. Print it with a brim and z-hop switched on: a small ring has a small footprint, and z-hop keeps a moving nozzle clear of what is already printed. The STL on its own is the smallest of the three. 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 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.

A 3x3 clicker pad: nine keys on one printed body, each on its own spring, so the whole thing clicks under a thumb like a tiny keyboard. 2.6" square, printed in one piece with nothing to assemble. Shown as a render, not a photo.
Design by Print3DFamilyFidgets
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.
Design by Timmy_1293
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
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 snake, printed flat as one piece: 9.8" from nose to tail, no supports anywhere, and off the plate in about an hour by its designer's own estimate. It prints lying on the plate, so the whole thing is one layer stack rather than a tower that can topple. Shown as a render, not a photo.
Design by user_3738174853
A textured clicker with a body and a set of button caps: the caps press into the body and click under a thumb, and the spare sizes in the set let you choose how stiff it feels. 2.6" long, printed in one go. Shown as a render, not a photo.
Design by ArmadilloFDM
A star that spins: the points are cut so it turns on its axis in the hand and keeps turning. Shown as a render, not a photo.
Design by CreaitivityStudio
A cactus that clicks: the body snaps onto a keyboard switch, so the whole cactus is the button and the click comes from the switch inside it. Four designs, sold one at a time - pick the cactus you want, about 1.3" tall, and it prints in two pieces that snap together without glue. Shown as a render, not a photo.
Design by UKSTL
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
A plain fidget spinner with no ornament on it at all: a body, three arms and a bearing seat in the middle. Five sizes come off the one plate, from a 1.6" one that fits in a pocket up to a 2.7" one, and the plate also carries the grips that go in the bearing seat. Pick the size you want - each is printed as one piece. Shown as a render, not a photo.
Design by MakerShed
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 pencil that bends: the barrel is printed as a chain of flexing segments, so it folds in your hand and springs straight again, and it still looks like a pencil with a point at one end. 4.8" long, printed in one piece. Shown as a render, not a photo.
Design by TinkerTogether
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.

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.

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.

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 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.

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 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 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.
