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 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.

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

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

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

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 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

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

The little tool for pulling the PTFE tube out of a Bambu A1 hot end without taking the printer apart - slot it behind the collar and lever. 1.7" long, printed in one piece in a minute or two. Remixed by R3DPanda from their own earlier version with a handle.

A jeep-bodied duck, cap and all - the joke that gets left on other people's cars, printed in one piece.

Design by 5er

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 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 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 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 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

An arrow holder that takes up to twelve arrows, for shafts up to 11/32 of an inch across. One arrow or a dozen loaded on the same side, it stays upright, and it needs no supports; the designer printed his on an A1 mini. It is not a frugal print - the designer says so himself - so it is priced by what it weighs rather than by the pose.

A 1/64 scale tanker for the Dragon Railway: the tank, its chassis, walkway and bogies across three plates, about 98 g of plastic. The designer's own profile runs 0.08 mm layers, for the surface the model deserves. It runs on the Dragon Railway bogies and autocouplers, which are separate prints.

Design by RamBros

Ballasted track sections for the Dragon Railway at 1/64: six straight lengths from 50 mm to 300 mm, each printed with its ballast shoulder moulded on, so a layout needs no loose gravel. The set is the six lengths the designer's plate holds, and his recommended minimum radius is 400 mm. The curved sections live in his second file, which prints a whole loop at once - that is a custom print rather than a shelf item, so ask for a quote and the shop will run the curves you need.

Design by RamBros

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 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).

Design by CippyO

A flower-petal stencil 0.8 mm thin, for tracing or airbrushing onto paper, cake or a wall. 3.8" across, printed flat in one piece - thin enough to lie flush on the surface. Shown as a render, not a photo.

Design by Merilno3D

A squeezer that slides up the tube as it empties: the roller presses the paste forward and the key at the end hooks over a rail so the tube hangs. 2.9" long, printed in one piece with the edges rounded so it does not catch on the shelf. Remixed by Weisnetde from two earlier squeezers, all under the same licence. Shown as a render, not a photo.

Design by Weisnetde

A little alligator printed as a chain of flexing segments - ridged back, four stubby legs and a tail that swings - so it wriggles across the desk and settles into whatever shape you leave it in. 2.4" long, printed in one piece. Shown as a render, not a photo.

Design by Litolunar

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 baby spike dragon with a ridged back and a curled tail, small enough to sit on a desk or ride on a keyring. 1.9" long, printed in one piece at high detail. Shown as a render, not a photo.

Design by BashStudio3D

A little octopus printed as a chain of flexing segments, so its eight arms trail and curl behind it. 2.2" across, printed in one piece in a single colour or with the body and the arms in different ones. Shown as a render, not a photo.

Design by slavko

Twelve little pals off one plate, each about two inches across and printed as a single piece, with no supports and nothing to assemble. Pick the one you want - the size on each chip is that pal's own width by height, so a 2.8"x1.6" one is a different creature from a 2.0"x1.4". Shown as a render, not a photo.

Design by Apricity

A pocket divot tool with a ball marker that sits in the handle: the fork lifts the green back into shape, the marker pops out to mark your line. 2.7" long, printed as two pieces. Shown as a render, not a photo.

Design by bitclicker

A water dragon printed as a chain of flexing segments - ridges along the back, a finned tail, and no supports anywhere. 4.5" long, printed in one piece, and it settles into whatever shape you leave it in. Shown as a render, not a photo.

Design by TinkerTogether

A penguin that comes apart into a stack of rings and goes back together again - the plate carries the body, four rings and the little caps, so it builds up and knocks down like a nesting toy. About 3.6" across the widest ring. Shown as a render, not a photo.

Design by katinkus

A baby hippo printed as a chain of articulated segments - stubby legs, a rounded snout and a tail - so it waddles about on a desk and settles into whatever pose you leave it in. 1.4" long, printed in one piece with no supports, in one colour or painted. Remixed by Joshuaisodd from Whitney Richmond's "Baby Hippo", sold under the same licence. Shown as a render, not a photo.

Design by Joshuaisodd

A hook remover with a forked end for backing a hook out and a flat end for pushing it through - the tool that means you do not put your fingers near the point. 4.8" long, printed flat in one piece. Shown as a render, not a photo.

Design by eclien

A lizard printed in one piece with no AMS and no supports - ridged back, splayed feet and a tail that curls, sitting flat wherever you put it. Three sizes: 1.7", 3.7" and 4.6" long, the smallest small enough for a keyring. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by AmandaRoos

A bunny printed as a chain of flexing segments with a carrot to go with it, so it curls up in your hand and springs straight again. The set prints as one plate - a 2.4" bunny and its carrot - and comes in a single colour or with the parts in different ones. Shown as a render, not a photo.

Design by TinkerTogether

A baby dragon sitting up with its little wings folded and its tail wrapped round its feet. 2.1" tall, printed in one piece with no supports, so it stands on a desk on its own. Shown as a render, not a photo.

Design by CLUCKWORKS3D

A bit holder that clips to a Ryobi ONE+ battery: the mount takes the loose bits you are using and keeps them on the drill, so they travel with the tool rather than in a pocket. 2.1" long, printed in one piece. Shown as a render, not a photo.

Design by Terrain 6

A screw toy for small hands: three chunky bolts with matching nuts, the caps they screw into and a long threaded rod - the plate is the whole set. The rod is 7.1" long, and every part is printed oversized so a toddler can get a grip on it. Shown as a render, not a photo.

Design by hyperZ

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 jellyfish with a dome for a head and four little tentacles, printed in place on a round stand so it hovers on a desk. 2.3" across the stand, printed as one piece with the tentacles already free. Shown as a render, not a photo.

Design by slavko

A little bear printed as a chain of flexing segments, with a loop through the top for a keyring - no supports anywhere. 2.2" tall, printed in one piece, and it wriggles when you hold it by the tail. Shown as a render, not a photo.

Design by TinkerLink

Nine flat dinosaur shapes, 1.6 mm thick and about 4" across, printed as a sheet you colour in and stand up. A pack for a rainy afternoon: colour them, cut them out, stick them to the fridge. Shown as a render, not a photo.

Design by Merilno3D

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.

Design by Pistachio

Shims for levelling a cabinet, packing a hinge or shimming a door frame. One plate is four shims - 42 x 89 mm, one each at 1 mm, 2 mm, 3 mm and 5 mm thick - so you pick the thickness that squares the job up instead of stacking paper. Shown as a render, not a photo.

Design by 3dprinting

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.
