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 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

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 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 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 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 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

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

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

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

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 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.

Design by CLUCKWORKS 3D

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.

Design by Bash Studio 3D

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.

Design by Big-D-SyneS

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 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 baby dragon 3.9" long, printed in one piece. Two versions come off the plate: the flexi one is a chain of segments that curls and straightens in your hand, and the solid one is a single rigid body with the same shape. Pick which you want.

Design by Quantrex

An articulated gecko 7.7" long, printed in one piece with every segment already moving - it curls over a shelf edge, drapes across a monitor and stays where you leave it. The plate also carries its little tongue.

Design by KrisCyber

A 1:20 pallet, 50 by 55 mm, for an RC forklift or a shelf of scale freight. It prints with no supports and, at two walls with solid bottom layers, comes out solid through the body. The proportions follow a UK-style pallet rather than a North American one. Designed by CippyO and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A 1/64 scale GP60B diesel for the Dragon Railway: the body, the bogies and the small fittings, printed across five plates, about 191 g of plastic in the set. It is a layout model rather than a toy that survives a floor, and RamBros publishes an assembly manual and a video covering the parts it wants.

Design by RamBros

A bat whose wings are cut into linked segments, so they flex when it is handled and settle into a curve on a shelf - printed in one piece with every joint already free. 3.9" across the wingspan, about 7 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.

Design by Tybob24

A bookmark of a book with a coffee cup resting on the stack - flat, 3.7" tall, and thin enough that it does not mark the pages. Printed in one piece in about a minute. Shown as a render, not a photo.

Design by giessener

A flat floral bookmark: one thin spray of three openwork blossoms and leaves that lies between the pages and reads against the paper, marking the page without thickening the book. 5.9 x 4.4" overall and 1.6 mm thin, printed flat in one piece in a few minutes. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Rankhispano

A pencil cup wrapped in overlapping scales, so it reads as a little pinecone on the desk while holding a fistful of coloured pencils. 3.3" across and 3.1" tall, 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 impresionao

An anatomically correct spine in print-in-place articulated segments: it flexes, curls and holds whatever pose you leave it in, with no assembly. Full runs 10.5" top to tail; Mini is 6.1". Shown as a render of the printable model, not a photograph.

Design by IndigoRaptor

A baby dragon that prints in one piece, with an articulated spine so the neck, wings and tail all bend and the whole thing can drape over a finger. It sits, curls and lies down, and needs no assembly and no supports. The picture is a render of the printable model, not a photograph of a finished print.

Design by Helios3D

A desk golf set in eleven printed pieces: a green you can rearrange piece by piece, a ball, a club and the furniture around it. About 3" a piece and 115 g of plastic for the set. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by SakiSale

A giraffe lying down with its neck folded back and its legs tucked - printed as a chain of segments, so it flops about when you pick it up. 6.5" long, and the eyes print as separate 8 mm pieces that go in after. Shown as a render, not a photo.

Design by SHF3D.

Four plectrum shapes, two of each, printed flat as one sheet: a teardrop, a jazz point, a wide triangle and a rounded standard, at 1.0 and 1.4 mm so a player can find the thickness they like without buying four packs. Each pick is about 34 mm long and the texture on the back of the thicker ones keeps a sweaty thumb where it belongs.

A practice mute for trombone, printed in three parts: the long tapered body that goes down into the bell, the flared cup that caps it, and the small collar that keeps the two together. 250 mm long and 193 mm across the cup, so it takes a full-size bell. The cup is what does the muting, so the horn can be played in an apartment without the neighbours learning the set list.

A pick holder with four feet that stands on an amp or a desk: slanted slots take plectrums by the tip so they can be pulled out one at a time, and the block is 90 mm long, 28 mm wide and 12 mm tall. The slots are cut at an angle, which is what stops a pick sliding back down into the holder. Designed by gareth7562 and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A plectrum printed flat at half a millimetre, 27 mm tall and 24 mm across, with the designer's design across the face - the pun in the name is the whole idea. Thin picks bend more than thick ones, so this is the one for strumming rather than for shredding. Designed by marshal.meacham and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A capo in two printed parts: a jaw that sits across the strings and the lever that clamps it down, 92 mm wide so it spans a standard six-string fretboard. It goes on the neck above the fret and holds the strings at the new position, which is what lets one shape be played in any key.

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 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 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 chunky little turtle with a big head, four stubby legs and a tiny tail, and a keyring loop moulded into its shell, so it sits on a desk or dangles off a bag. It is 1.6" by 1.2" and prints in one piece with nothing to assemble. Shown as a render, not a photo.

Design by Type1Printing

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 segmented caterpillar that wriggles: every segment is jointed to the next, printed as one piece with nothing to assemble and no supports, so it comes off the plate already moving. Two lengths - the short one at 5.4 inches and the longer twelve-segment version at 7.2 - and the longer one is the one to buy if you want it to drape and coil in your hand. Prints at 0.2 mm layers in PLA, and it takes a colour change well if you want the segments striped. 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

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.

Design by goatbuster

A baby stone dragon in one piece: the plates of its body are jointed all the way down, so it curls and straightens and holds whatever shape you leave it in, and it stands on its four legs because the legs are part of the same print. This is the wingless one, so nothing catches on a sleeve or a shelf. Two sizes - 4.2 inches and a 2.5 inch pocket-sized version - both printed in place with no supports. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Bash Studio 3D

An articulated baby dragon: the body, tail and neck are cut into segments joined by print-in-place hinges, with the head and its small horns on top. It is 4.5" long and prints in one piece. Choose the finish: solid is the plastic alone, and each extra colour is a filament change at the printer, charged at the shop's $1 a colour. Shown as a render, not a photo.

Design by BashStudio3D

A small hook that sticks to a desk or a shelf edge with tape or a screw, for keys, headphones or a cable. 2.6" wide, printed in one piece with a flat back that sits flush. Shown as a render, not a photo.

Design by schiko

A B2 in flying-wing form that sits on top of a joystick - the shape slots over the stem and pegs in, so it turns with the stick. 5.5" across the wings, printed in one piece plus two pegs. Shown as a render, not a photo.

Design by DeanPrinting

Design by SHF3D

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 caterpillar printed as a chain of flexing segments with a face at one end, so it wriggles along your hand and curls up when you put it down. 6.7" long, printed in one piece, with no supports and no assembly. Shown as a render, not a photo.
