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.

A strip that threads onto a guitar strap and holds a stack of picks, so a fresh one is within reach in the middle of a song: 100 mm long and 25 mm wide, printed in one piece. It sits on the strap rather than in a pocket, which is where picks go to be lost. Designed by willywidget and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

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.

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 medal rack: two upright spines joined to a flat back plate, with a hooked arm either side of each spine so medals hang in a row instead of sliding into a heap, and the back takes a screw or a strip of tape. About 9.5 inches wide - a whole season of races hangs off it. Designed by donnkey - a remix, in their words, of Alan Břuska's "Věšák na medaile - Medal hanger" on Printables - and printed under CC0. Shown as a render of the printable model, not a photograph.

A stackable glasses stand: a fin that the cradles slide onto, so the tower grows to whatever height the collection needs. The cradles come in three widths - 67, 77 and 87 mm - and each holds one pair nose-down by the bridge, which suits slim readers and deep sunglass frames alike. The plate prints a whole tower's worth of parts, 167 by 199 mm laid out as the designer arranges it.

A capo in two printed parts: a jaw that sits across the strings and the lever that clamps it down, 92 mm wide so it spans a standard six-string fretboard. It goes on the neck above the fret and holds the strings at the new position, which is what lets one shape be played in any key.

A glasses rack that lives on the wall: six cradles in a row on one 210 mm plate, 22 mm deep, so six pairs hang out of the way of a counter or a bedside table. It prints as one piece with nothing to assemble, and the arms take wire or plastic frames by the bridge. Designed by Matthew and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A plectrum printed flat at half a millimetre, 27 mm tall and 24 mm across, with the designer's design across the face - the pun in the name is the whole idea. Thin picks bend more than thick ones, so this is the one for strumming rather than for shredding. Designed by marshal.meacham and printed under Creative Commons Attribution 4.0 (CC BY 4.0).

A small square gift box, about 60 mm across and 50 mm deep, with a lid that sits a little proud on purpose so it lifts off easily. The bow and the little tree decoration print as separate pieces, so the box can be used plain or dressed up - all four pieces come as the set, and there is room inside for a ring, a pair of earrings or a few chocolates.

A modular glasses stand: a round 143 mm base with a spindle, a post that carries two long arms, and a cradle that stacks on the spindle, so two pairs or a shelf-full can be kept upright and out of the way. The arms take frames by the bridge and the base is heavy enough not to tip when one pair comes off.

A pick holder with four feet that stands on an amp or a desk: slanted slots take plectrums by the tip so they can be pulled out one at a time, and the block is 90 mm long, 28 mm wide and 12 mm tall. The slots are cut at an angle, which is what stops a pick sliding back down into the holder. Designed by gareth7562 and printed under Creative Commons Attribution 4.0 (CC BY 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.

Four plectrum shapes, two of each, printed flat as one sheet: a teardrop, a jazz point, a wide triangle and a rounded standard, at 1.0 and 1.4 mm so a player can find the thickness they like without buying four packs. Each pick is about 34 mm long and the texture on the back of the thicker ones keeps a sweaty thumb where it belongs.

A practice mute for trombone, printed in three parts: the long tapered body that goes down into the bell, the flared cup that caps it, and the small collar that keeps the two together. 250 mm long and 193 mm across the cup, so it takes a full-size bell. The cup is what does the muting, so the horn can be played in an apartment without the neighbours learning the set list.

A desk caddy printed in one piece: a raised back that stands a phone at a reading angle, a round well for pens, and a square tray for a watch, keys or a card, with a slot for a charging cable to pass through. It is 7.1" wide by 3.5" deep. Shown as a render, not a photo.

A planetary gear set printed in place: six small gears mesh between a sun gear and a toothed ring, so turning any one of them turns all the rest. It is 2.5" across and prints as a single piece with nothing to snap together. Shown as a render, not a photo.

A phone stand that folds out of a keychain: the plate swings up and the phone leans back on it, and folded away it hangs on your keys. 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.

A graduation cap and gown on a keyring: the mortarboard tilted over the gown, with a class year or a name across the front on the version the designer included for it. It hangs flat and reads clearly from a distance, which is what a keepsake for a graduate wants to do. Printed as one tag with the layered faces so the cap, the gown and the lettering each read separately. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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 keyring that opens without a metal split ring, printed as one piece with nothing to assemble. The flat band is broken once, and across that break the two ends lap through the ring's own thickness - the socket keeps the lower half, the near end the upper, with a quarter of a millimetre of air between them - so the finished ring reads as one band with a hairline in it rather than two pieces butted together. What holds it shut is the gate's own end, narrowed to a tongue: the band's inner and outer edges step down either side of it, and the tongue carries a rounded bump underneath that sits in a seat cut into the socket. Flex the ring apart and the bump rides up its own rounded side, which is a detent and not friction; let go and it drops back in. The tongue is relieved with a round hole at its root, because that is where it bends when you press it up to open the ring. Flex it, thread your keys on, squeeze it shut. The picture is a render of the printable model - real photographs of the print go up once the first batch comes off the printer.

Five heart shapes, each layered front to back so the colours read as depth: black sits at the back as the outline and the two layers in front are yours to choose, so one colour is the simplest and three makes it pop. Pick the shape you want - each is about 1.6" by 1.5", with a loop for a keyring or a chain. 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.
