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 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 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.

A flat key tag that holds the key by its bow rather than its ring, so it lies flat in a pocket and does not rattle. 2.2" long, about 1 g of plastic, printed in one piece. Shown as a render, not a photo.

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 dragon in a coiled pose, wings half-open and tail curling round to its head - a display piece rather than a toy. 9.5" across and the biggest thing on the shelf, printed in one piece. Shown as a render, not a photo.

Design by mdesign

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 thin blade for digging the lint out of a phone's charging port, with a hook at one end and a flat scraper at the other. 34 mm long and a fraction of a gram, so it prints three at a time in a minute - one for the desk, one for the car, one to lose. Shown as a render, not a photo.

Design by eclien

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

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 beer crate for batteries, scaled down to sit on a shelf: stacked sides, a slotted top and a handle you can actually lift it by. Holds a row of AA or AAA cells - pick which, they are separate crates. About 2.7" long. Shown as a render, not a photo.

Design by JSBallpython

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 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

A ruler that folds: nineteen 160 mm segments that hinge end to end, plus the two end caps, so it measures a room and then folds down to a pocket. The full set is 19 segments; the smaller option is the same design at 70 per cent, which is the one for a desk drawer. Shown as a render, not a photo.

Design by PenguinPrototypes

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 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.
