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.

Sixteen ring gauges from 15.4 mm to 27.6 mm across, printed flat on one plate so you can measure a finger properly instead of guessing. The whole set is about 6 g of plastic - print it once and keep it in a drawer. Shown as a render, not a photo.

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 two-prong hair pin that holds a bun without a single elastic - the forks flex, so it grips and then lets go. Two lengths: 4.5" for fine or shoulder-length hair and 5.9" for thick or long. Printed flat in one piece, in one colour or two. Shown as a render, not a photo.

Design by riverbed

A teepee that holds the spare rolls: two printed panels hinged into a tent, a base that keeps it square and three dowels that peg it together, with a roll inside. 6" across and 5.3" tall, printed in panels and assembled - the modular system, in the size that fits a small printer. Shown as a render, not a photo.

Design by ThePhilosopher

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 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.
