A jack-o-lantern that drowns fruit flies: bait goes in the cup, the lid funnels them down and they cannot get back out. 2.7" across, printed in two pieces with no supports - and it earns its place on the counter for a fortnight in October. Shown as a render, not a photo.

Design by PolaQ

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

Six coasters shaped like leaves, 70 mm across and 3 mm thick, each with a different vein pattern. Printed flat with no supports, and thin enough to stack in a drawer. Shown as a render, not a photo.

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

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.

Design by IvanChamberlain

A 608 bearing that prints already assembled - the races, the balls and the cage all come off the plate as one piece, and it turns as soon as you break it free. 22 mm across, 7 mm thick, the size a fidget spinner or a skate wheel takes. Shown as a render, not a photo.

Design by Jerryie

A hose clamp you print instead of buying: a ring with a screw lug that tightens onto a hose or a duct. Four sizes, measured across the clamp - 33 mm, 40 mm, 60 mm and 88 mm - each printed in one piece. 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

Seven traditional Christmas shapes, each about 3" across, printed with a cutting rim and a handle you can press. Cut a whole tin of mixed biscuits from one set. Shown as a render, not a photo.

Three sculpting tools with different ends - a flat blade, a point and a loop - for clay, fondant or plasticine. About 6" long each, printed flat in one piece, so they are light enough to work with for an hour. Shown as a render, not a photo.

Design by Chilly_275

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 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 table number: the digit cut as one flat plate inside an ornate oval frame, standing in a round base. Pick the number you need - every digit from 0 to 9 - and it arrives as the frame and its base, ready to slot together. About 5 inches tall, so it reads from across a room without sitting between two guests. Designed by swirly1007, who made the set for their daughter's wedding, and printed under Creative Commons Attribution 4.0 (CC BY 4.0). Shown as a render of the printable model, not a photograph.

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.

A workshop set of ISO 4017 hex-head screws in M3, M4, M5, M6, M7, M8 and M10, each size on its own plate, so you print the sizes you need and keep a jar of spares. The whole set is seven plates and about 55 g of plastic; the M10 is 2.8" long. Shown as a render, not a photo.

Design by Jerryie

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.
