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.

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.

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.

A football cake topper - a player, a ball and the words Happy Birthday - printed flat as one piece that stands in the cake. 5.5" wide, about 6 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.

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 napkin holder with a voronoi lattice for walls - it holds a stack of napkins and looks like something grown rather than built. 5.1" long, printed in one piece. Shown as a render, not a photo.

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 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.
