Design by user_4069524941

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

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 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.

Design by ValeraPerinski

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

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 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

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 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 cap that turns a jar into a fruit washer: fill it, shake, and the water spins the berries clean instead of bruising them. The cap and its inner piece print together in one go - size L fits a standard wide jar. Shown as a render, not a photo.

Design by ValeraPerinski

Ten layered fidget discs off one plate - each about 3" across, each with its own cut-through pattern and its own way of spinning and clicking. Pick the design you want; the picture on each chip is that disc. Shown as a render, not a photo.

Design by PenguinPrototypes

A kitchen roll holder with a weighted base: the disc takes sand or coins, so the roll stays put while you pull one sheet off with one hand. 9.1" tall, printed as a base and a post. Shown as a render, not a photo.

Design by MicahW3D

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 fridge egg dispenser: eggs roll down a ramp and out of the front one at a time, so the oldest is always the next to come out. 9.7" long and holds a dozen, printed in three pieces - the ramp, the body and the front cup - with no supports. Shown as a render, not a photo.

Design by specialman

An upright organizer for the utensils that live on the counter: compartments of different heights, a flat back to go against a wall, and a base wide enough that a ladle does not tip it. 8" long, printed in one piece. Shown as a render, not a photo.

Design by lunatiic

A ball that screws into its own cage - the thread holds it, and it spins from one end to the other without ever coming free. 3.9" tall, printed in place in two pieces that come off the plate already assembled. Shown as a render, not a photo.

Design by Elaak

A holder that stands cutlery up in a drawer or on a counter, with slots for forks, knives and spoons and a low front so you can see what you are reaching for. 5.9" long, printed in one piece. Shown as a render, not a photo.

Design by Alex

A rest for a wooden spoon: the bowl sits in the cradle and the handle lies over the rim, so the drips land in the holder instead of the hob. 4.7" across, printed in one piece. Shown as a render, not a photo.

Design by Jirka108

Four wedding cutters with stamp inserts - the ring, the cake slice and two more - for biscuits at an engagement or a hen do. About 3" across each, and the same set cuts playdough for the small guests. Shown as a render, not a photo.

Design by Nix3D

An impossible passthrough wound as a spiral: the helical parts turn through each other and hold, printed in one piece. 2.8" tall, about 29 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 BeninManc

A mini golf hole for the desk: a printed course board with the hole and a rock surround, a club and a ball, all printed flat. 8.7" x 7.2", about 62 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 MoltenPlastic3D

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 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 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

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

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

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 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 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 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

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

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

A jack-o-lantern that drowns fruit flies: bait goes in the cup, the lid funnels them down and they cannot get back out. 2.7" across, printed in two pieces with no supports - and it earns its place on the counter for a fortnight in October. Shown as a render, not a photo.

Design by PolaQ

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 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

Two holders that keep takeaway lids upright and sorted instead of sliding about in a drawer - one for the small lids, one for the large. 6.8" and 4.8" tall, printed as a pair; the designer measured them for Tesco containers. Shown as a render, not a photo.

Design by FaasteerCZ

A gripper that clips two chopsticks together into one easy pair - for a child learning, or anyone who has given up on holding two sticks. 1.4" across, printed in one piece, and the large and small blanks are on file for different stick thicknesses. Shown as a render, not a photo.

Design by RynoRC

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

Four bee-and-honeycomb cutters with stamp inserts - the bee, the flower and two honeycomb shapes. Press the stamp for the detail, cut the outline, bake; each is about 3" across. Shown as a render, not a photo.

Design by Merilno3D

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

Four bug cookie cutters with matching stamp inserts - cut the outline, press the details, bake. Each about 3" across, and the same set works for playdough, which is what the designer made it for. Shown as a render, not a photo.

Design by Merilno3D

A free-standing kitchen roll holder: a weighted base and a post that takes a standard roll, so the paper comes off one-handed. 8.3" tall, printed in one piece - the stand-alone version needs no wall fixing. Shown as a render, not a photo.

Design by R3Designs

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 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

Eight bunny cookie cutters, each with a stamp insert - press the face and ears, cut the outline, bake. About 3" tall each, and the same set cuts playdough, which is what the designer made it for. Shown as a render, not a photo.

Design by Merilno3D

Design by MeltedMoose
