A pair of arrow earrings, each with a coiled shaft, a small loop at the tip for the hook and a heart-shaped flight. They print flat and weigh well under a gram for the pair, so they want hooks or studs fitted afterwards. Each is 2.1" by 0.7". The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own.

Design by TinkerTogether

A Spartan helmet in profile, crest and all, 2.2" tall, with a loop at the top so it hangs as a pendant or swings on a keyring. It prints flat in one piece, which keeps the crest and the cheek guard crisp.

Design by OrangeSs

A bowl for rinsing rice: the water swirls through the grain and pours off the side while the rice stays put, so you stop losing half of it down the sink. Two sizes - 6.9" across and a smaller 4.8" - each printed in one piece, with the drain holes and the pouring lip part of the bowl.

Design by ValeraPerinski

A plump bee that clips onto the top of a straw, wings raised and its stripes cut deep enough to read across a table. It suits the 10 mm Stanley straws, is 1.6" by 1.5", and prints in one piece with no supports.

Design by Morganja

A dog's head that sits on top of a straw, ears up and nose forward.

Design by Morganja

A low-poly Labrador, faceted like cut stone, standing with its head up: the low-poly build keeps it light enough to print and lets it catch the light along the facets. Two sizes - the big one at 4.7" tall and a pup at 2.4" - each printed in one piece.

Design by CreaitivityStudio

A Jeep grille that rides on top of a straw, seven slots and all.

Design by Morganja

A jeep-bodied duck, cap and all - the joke that gets left on other people's cars, printed in one piece.

Design by 5er

A pencil holder wearing a puffer jacket: quilted panels all round, with a zip, a collar and sleeves running up the sides. It holds pens, pencils, markers, brushes or small tools, and it is sturdy enough to be knocked about a desk. About two hours of printing, and the quilted panels take filament colours well - solid winter colours, pastels, or something loud.

Design by Sitsero

Two spirals in one print: an outer shell that twists one way and a core that twists the other, turning past each other as you fiddle. Printed in a single colour it reads as one tapering cone; give the shell and the core a colour each and the two spirals separate in the eye as they turn, which is what the designer's own pictures show. The profile that prints it is 0.2 mm layers, 3 walls, 15 per cent gyroid infill, PLA, no supports, standing upright exactly as supplied.

Design by NerdHerder

A printable reading ruler with an integrated bookmark pointer. The pointer holds your line while you read and marks your place when the book closes - pick the length that suits your book.

A lid that snaps onto a standard can and seals it up again between sips, and doubles as an opener when you slip it over the tab and tilt. It is the wider, support-free version, and it fits both the slim and the fat cans the designer built it around - European 202 cans, so if yours is a different can it is worth a quick measure. Light sanding on the slots is the only finishing it asks for.

Design by MakerShed

A push-fit cover for the Tesla Cybertruck's front tow hook recess, so the bumper reads as one clean line instead of an open slot. It clips in with a lip at each end and no hardware. Choose the material: PETG shrugs off sun and road salt, PLA is the everyday version at the same price. The prototype in the video carries the name "Shadowfax" embossed into its face - that was that truck's own, and yours can have a word of its own cut the same way: type it while you are adding it to the cart, up to 12 characters, +$10. A personalized cover is made to order, so it is paid online rather than reserved for cash at pickup. Leave it blank and the face is plain.

A gyro fidget spinner: three curved rings interlock around a centre post and whirl as one, so it prints in a single piece with no bearings and no assembly - just flick it and go. The rings are loose in their track out of the printer, which is the part that takes a few tries to get right and the reason this one gets measured before it ships.

A one-piece beard comb with rounded teeth that glide through without scraping. Small enough to live in a jacket pocket, and it prints without supports. The solid band above the teeth can carry a name, cut into the surface rather than raised, because a comb lives in a pocket and raised letters are the first thing to wear off: type the name while you are adding it to the cart, up to 12 characters, +$5. A personalized comb is cut to order, so it is paid online rather than reserved for cash at pickup. Leave it blank and it comes exactly as the photos show it.

An impossible passthrough built as a pyramid: the parts pass through one another and no amount of turning lets them go. 2.8" tall, about 21 g of plastic.

Design by BeninManc

An impossible passthrough shaped like an hourglass: two halves that turn through each other and stay locked together. 2.8" tall, about 24 g of plastic.

Design by BeninManc

Four dinosaur cookie cutters with matching stamp inserts - press the stamp for the details, cut the outline, bake. Each cutter is about 3" across, and the set is four different animals.

Design by Merilno3D

A hard hat that goes on a keyring - the dome, the brim and the little ridge down the middle, printed in one piece with a hole through the top. 1.5" across, and it works as a key tag or a desk charm.

Design by astavr

A clip-on egg separator: crack an egg into the channel and the white runs through while the yolk stays put. 3.6" long, printed in one piece, and it sits on the rim of a cup or a bowl.

Design by user_4069524941

A smiley you can click: the face is the button, and it presses in and springs back with a sound. 3.2" across, printed in one piece with no AMS and no supports. Shown as a render, not a photo.

Design by AmandaRoos

A 2 mm PLA cake stencil, 6 x 4 inches, with Happy Birthday and three balloons cut right through. The lettering is a stencil face, so the middles of the a, p, B, R and D stay attached to the plaque instead of falling out. Lay it on a sheet of parchment over the cake, dust with cocoa or icing sugar, and lift it away. Four or more come at the bulk rate. The picture is a render of the printable model, not a photograph; real photos go up once the first one is printed.

Four bee-and-honeycomb cutters with stamp inserts - the bee, the flower and two honeycomb shapes. Press the stamp for the detail, cut the outline, bake; each is about 3" across. Shown as a render, not a photo.

Design by Merilno3D

A gripper that clips two chopsticks together into one easy pair - for a child learning, or anyone who has given up on holding two sticks. 1.4" across, printed in one piece, and the large and small blanks are on file for different stick thicknesses. Shown as a render, not a photo.

Design by RynoRC

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.

Design by HurtTree

Two holders that keep takeaway lids upright and sorted instead of sliding about in a drawer - one for the small lids, one for the large. 6.8" and 4.8" tall, printed as a pair; the designer measured them for Tesco containers. Shown as a render, not a photo.

Design by FaasteerCZ

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.

Design by Maker76

A flat key tag that holds the key by its bow rather than its ring, so it lies flat in a pocket and does not rattle. 2.2" long, about 1 g of plastic, printed in one piece. Shown as a render, not a photo.

Design by Katejot2017

The classic folded awareness ribbon with a keyring loop at the top, printed flat so the fold reads cleanly on both faces. It is 2.5" long by 1.4" wide and prints in whatever colour you choose. Shown as a render, not a photo.

Design by Miss3DP

A layered volleyball charm: the ball's panels are cut as separate raised layers, so the seams read as depth rather than a printed line. It is 1.6" by 1.4", has a hole at the top for a ring or a chain, and prints flat in one piece. Shown as a render, not a photo.

Design by CoisinhasdaManu

Three holders that keep bottles lying down in the fridge instead of rolling out of the door - each cradles one bottle on its side and stacks with the others. The plate prints three, and each is about 9.4" long. Shown as a render, not a photo.

Design by RossMacAllan

A paw that rides on top of a straw: the straw passes through the middle of it, the paw sits above the lid, and the raised pad and four toes catch the light as the cup moves. It is made for the 10 mm Stanley straws, 3.5" tall by 1.6" across, and it prints in one piece. Shown as a render, not a photo.

Design by Morganja

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.

Design by jdormer9

A hexagonal tube cut into one continuous spiral, so it springs and flexes in the hand and the turns of the helix roll past each other under a thumb. It prints as a single piece and needs no assembly, and it stands 2.8" tall by 1.3" across. Shown as a render, not a photo.

Design by NerdHerder

Eight sports-ball charms, each with the ball's own surface cut into it - soccer pentagons, a golf ball's dimples, a basketball's seams - so they read as the real thing at charm size. Pick the one you want: every ball has a hole for a keyring or a chain, prints flat with no supports, and measures about 1.7" by 2". Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

A fidget spinner small enough to live in a pocket: one piece, no bearings, no axle to glue, printed in place so the two halves and their weights come off the plate ready to spin. It is a 15-minute print in the designer's own profile, which is why it makes a good giveaway or market-stock item. Printed in a silk filament the spinning face catches the light. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DragonFusion3D

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 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 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.

Design by musielovsky

Twenty-six dog charms, each cut with a different dog in relief so it reads at a glance on a keyring or a necklace - the designer's three sets, in one listing. Pick the dog you want: every one has a hole at the top for the ring or the chain, prints flat with no supports, and measures about 1.4" by 2.4". Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

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

An elephant charm in flat relief, trunk curled, with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

Love hearts, one letter at a time: A to M, each a heart-shaped charm with the letter cut into it, so a name or a message is spelled out a charm at a time. About 1.6" by 1.6" each, with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A turtle small enough to sit on a shelf edge: the shell is modelled with its own scutes and the head, tail and legs are all there, so it reads as a real turtle rather than a toy one. 2.3" long and printed in one piece. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by Type1Printing

A corgi that keeps the bread shut: the body is the clip, the ears are the handle and it sits on the bag like a peg. 5.4" long, printed in place in one piece. Shown as a render, not a photo.

Design by Burak19891

A pair of open heart outlines, each about 1.9" by 1.6" and barely over a gram, with a small hole at the top for the ear wire. They print flat, so the outline stays crisp and there is nothing to finish beyond fitting the hooks. The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render, not a photo.

Design by C4UStudio

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.

Design by Morganja

A star that spins: the points are cut so it turns on its axis in the hand and keeps turning. Shown as a render, not a photo.
