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.

A modular hydroponic tower printed as twelve parts: a base, the column that stacks, five growing cups and the plates that close the sides. The column is 220 mm across and 128 mm tall, each cup 55 mm. The modules come apart, so a tower can be built one section at a time and taken down again. Shown as a render of the printable model, not a photograph.

A print-in-place bag clip: the hinge prints shut and then works, so there are no pins and nothing to assemble. 3.2" long, 1.2" wide. Shown as a render of the printable model, not a photograph.

A mosquito trap that uses a jar you already have: a funnel that drops into a mason jar's mouth, so a jar of water and a spoon of sugar becomes a trap. The cone lets a mosquito in and the jar's own walls keep it there. Three funnels come off the plate, 76 mm across and 47 mm tall, for the jar sizes the designer covered - standard jam jars among them. Designed by IanFoulds, a remix of the Mosquito Trap by Urasxman, and printed under Creative Commons Attribution 4.0 (CC BY 4.0). Shown as a render of the printable model, not a photograph.

A mid-century planter with vertical ribs and its own drip tray, printed at 0.24 mm layers with two walls and 8 per cent infill - the profile the designer recommends for the balance between speed and detail. He also notes a 0.6 mm nozzle does the same job faster and builds just as solid, and that the model scales cleanly if you want it bigger.

Six mushroom shelves, each printed with its wall mount built in - no bracket to add and nothing to glue, so a screw in the wall is the whole installation. The caps come in six shapes and sizes, so they can run up a wall beside a plant or dot about independently. Designed by Dr.D, who remixed Moiras_creations' Mushroom shelves - both makers are credited on this page - and printed under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0).

A soap dish shaped like a leaf, with the veins textured into the face. The file carries two bodies - a flat textured dish and a deeper one - and both are printed, so you get the pair and can keep the shallow one for a sponge.

A taiko drummer whose drum is the holder: the hollow drum takes cotton swabs, and the figure's hands hold one snapped in half as a pair of drumsticks. Four printed parts - base, figure, drum and the rack behind him - and the drumsticks take a touch of glue to stay put, as the designer's own notes say. Sold as the set.

A pair of lips that sits on top of a straw: the straw passes through the middle and the lips ride above the lid, catching the light as the cup moves. It suits the 10 mm Stanley straws, is 3.9" tall by 2.2" across, and prints in one piece. Shown as a render, not a photo.

A round indoor pot with a pleated, fabric-like skirt, standing on its own matching base so it can be moved without leaving a ring on the shelf. Two pieces, both printed in the same colour, 4.6" wide and 3" tall together. Shown as a render, not a photo.

A six-can holder that spins: six runners hold the cans and the base turns, and it uses very little filament for its size. Four pieces. Shown as a render, not a photo.

A heart that sits on top of a straw, wide and low, catching the light as the cup moves. Shown as a render, not a photo.

A bow that clips onto a straw: the straw runs through the middle and the bow sits above the lid. Shown as a render, not a photo.

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.
