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 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 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

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.

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 golf tee with a ball sitting on its cup, printed as one piece - a desk trophy, a party favour or a cake pick as much as a tee. 2.3" tall, and barely a gram 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 LilÕJimbob

The 2 to 9 times tables on one flat plate, 5" x 3.6" and 1.6 mm thick - a card that lives in a pencil case rather than on a screen. Shown as a render of the printable model, not a photograph.

A reading guide that frames one line at a time so the page cannot swim: 5.1" x 1.4", 1.4 mm thick, light enough to leave in a book. Kept for kids learning to read, and for anyone whose attention slides down a full page. Shown as a render of the printable model, not a photograph.

A largemouth bass on a rock, mouth open, fins up, printed as one piece with the base built in: a shelf or desk piece for somebody who would rather be on the water. Two sizes, and both are measured off the designer's own files - 97 mm nose to tail, and 190 mm for the mantelpiece. The smaller one is the same mesh scaled down and supported, so the detail is the same at both sizes. Designed by AUTROJAN and printed under Creative Commons Attribution-ShareAlike 4.0 (CC BY-SA 4.0).

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.

Design by printerforge

A kicking tee for rugby: a 120 mm base with a stem that stands the ball at the angle a kicker wants, so a conversion or a kick-off starts from the same place every time. 110 mm deep and 72 mm tall, printed as one piece with a wide foot that will not skate on wet grass.

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.

Design by Fiteropp

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 hanging books-read counter: a sign with a row of numbers that slide into it, so the count can be moved along as the year goes. It is two plates - the sign with one of each number, and a second sign with the numbers again so the count can pass ten - and either can be bought on its own. Shown as a render, not a photo.

Design by ZHeights

A ghost bookmark: a flat spectre that hooks over the page, thin enough not to splay the spine. There are seven of them in the file, each a slightly different ghost, so pick the one you want - about 1.2" by 4" and printed flat. Shown as a render, not a photo.

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.

Design by Morganja

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.

Design by JEP0405

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.
