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 bag peg that works like a clothes peg: two arms on a printed pin, so the ends you squeeze and the jaws are on opposite sides of the pivot, and squeezing opens the jaws. A disc on the upper arm turns inside a socket on the lower one, printed in place with a quarter of a millimetre of air round it - press the peg open and you can feel the pin move. Behind it one strip sweeps round and back to the other arm as a scroll you can see through, and that scroll is the spring: it closes the jaws and it is what you feel working when you squeeze. The mouth is a square-wave channel cut through both jaws at once, so the two sets of teeth come from the same cut and interlock - every tooth of one jaw stands in the hollow of the other - and along the outside of each arm, where a thumb goes, a row of sawteeth bites into the silhouette so the peg does not slip in your hand. It prints flat as one piece, no supports, nothing to assemble. PLA holds fine; PETG survives the dishwasher and takes more flexing. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Candle holders that let the light out through the walls: a Voronoi web of gaps and ridges so the flame - a battery tealight, never a real one - glows through the whole shell rather than out of the top. The set is three holders, three diffusers and the base plate that carries them; print the holders in matte black and the diffusers in white, which is the pairing the designer built it around, and a single holder works just as well on its own. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

Design by DueMakers

Two cats curled into a heart, cut in relief so the tails make the shape. Pick the fitting: the keychain has a ring hole, the charm is sized for a chain. It prints flat with no supports, about 1.9" by 2". Shown as a render, not a photo.

Design by dominator334

Six St Patrick's Day charms from one plate: a clover, a horseshoe, a leprechaun hat, a shamrock shield, an Irish banner and a pot of gold. Pick the one you want - each has a hole at the top for a keyring or a chain, prints flat with no supports, and measures about 2" across. Shown as a render, not a photo.

Design by dominator334

A dragon printed as a chain of flat segments joined by print-in-place hinges, so the body ripples along its length and lies straight when it hangs still. It is 59 mm nose to tail and 8 mm deep at the head, prints in one piece with no supports, and a pair is two dragons. Shown as a render of the printable model, not a photograph.

Design by tomo3D

A chef's hat charm with a banded brim, tall enough to read at a glance on a keyring. Shown as a render, not a photo.

Design by Tim

A pair of eighth notes, each an outline rather than a filled shape, so they stay light on the ear and catch the light along the stem. Each is 20 x 22.7 mm and 2 mm thick, with the hole in the note head for a hook, and they print mirrored so the two notes sit opposite each other. Shown as a render of the printable model, not a photograph.

Design by mikesak29

A heart drawn in a few asymmetric arcs, 34 x 29 mm and 2.3 mm thick, with a hole at the top for a hook. The plate is a solid rim around a cut-out centre, so it reads as a sketch of a heart rather than a filled one, and the pair hangs light. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by Vulcain

A daisy with eight rounded petals and a raised centre, 35.6 mm across and 3 mm thick, printed with a matching stud so the flower sits on a post rather than dangling from a hook. The plate holds four flowers and four studs, which is two pairs; a pair is a flower and a stud for each ear. Shown as a render of the printable model, not a photograph.

Design by mhumphries1973

Two flip flops printed as one piece, each with a raised strap and a toe post standing up through the sole, so they read as sandals rather than flat outlines.

Design by tomo3D

XO in solid letters, 40 x 37 mm and 2 mm thick, with a small hole at the base of the O for a hook. The two letters are cut as one piece, so each earring hangs as a single word rather than two separate charms. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by SynneLuna

Six horse silhouettes as keychains, each a different pose cut in relief and each with a hole at the top for a ring or a chain. Pick the horse you want - they print flat with no supports and measure about 2.4" by 1.5". Shown as a render, not a photo.

Design by dominator334

A butterfly with its wings open and the veins left raised, so the pattern survives printing instead of filling in. Each is 49 x 31 mm and 1.6 mm thick, thin enough to sit flat against the ear, with a hole at the top for a hook. The pair prints as two mirrored butterflies. Shown as a render of the printable model, not a photograph.

Design by FrazierSmith

A six-fold filigree snowflake, 35 x 31 mm and 1.5 mm thick, with a hole at the top for a hook. Every branch is openwork, so it prints as fine line after fine line rather than a solid plate, and it catches the light as it moves. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by PediMR

Varsity letters as keychains: a block letter with a stitched look, cut in relief and about 2.4" tall. Pick the letter you want - A to M are here, and each has a hole at the top for a keyring or a chain. Four or more of any mix come at the bulk rate. Shown as a render, not a photo.

Design by dominator334

A bee with a rounded body, two wings standing off it and a hook hole at the head, printed as one piece at 25 x 29 mm. The body is domed rather than flat, so it reads as a bee from the side too, and it is light enough to wear all day. Order a pair and you get two. Shown as a render of the printable model, not a photograph.

Design by wally

A dolphin inside an oval ring, 42 x 37 mm and 2.6 mm thick, with a small eyelet at the top for a hook. The dolphin is cut clear of the ring behind it, so the two shapes read separately and the pair hangs as two clean outlines. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by Ghost1975w

A pair of sunglasses with the arms and a bridge moulded in, printed 2.5 mm thick and 32 mm across, with a hole in each arm for a hook. They are a joke that prints properly: the lenses are open, so the shape holds at this size and reads at a glance. Shown as a render of the printable model, not a photograph.

Design by tomo3D

A cat curled up as a charm, cut in flat relief so the shape reads at a glance on a keyring or a necklace. It prints flat with no supports and measures about 2.4" by 1.8". Shown as a render, not a photo.

Design by dominator334

A pair of leaf earrings: a pointed leaf with its veins cut into the face, light enough to wear all day at a bit over a gram the pair. They print flat with a hole at the top for the hook, so nothing else is needed but the ear wire. Each is 1.9" by 0.8". 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 watermelon slice with the rind standing proud of the flesh and the seeds cut into it, 26.7 x 25.9 mm and 1.6 mm thick with a hole at the top for a hook. The plate prints eight slices, which is four pairs; order a pair and you get two. Shown as a render of the printable model, not a photograph.

Sold as a set of three pairs - the large hearts for everyday, the two small pairs for a second piercing or to give away. Shown as a render of the printable model, not a photograph.

Design by Merche

A filigree arch: a curved band of scrollwork with the spaces cut right through, so it reads as lace from the front and sits like a crescent against the ear. Each is 26 x 34 mm and 2.3 mm thick with the hook tab at the top, and the pair is mirrored. Shown as a render of the printable model, not a photograph.

Design by Vulcain

One continuous line draws a face in profile, cut out flat as an earring: 26 mm tall, 2 mm thick, with a hole at the top for a hook. Sold as a pair, mirrored so the two faces look at each other. Shown as a render of the printable model, not a photograph.

Design by Margen3d

Design by ProtoEngineering

Four feather shapes, each printed twice so every design makes a mirrored pair: 60 mm long, 2 mm thick, with the barbs cut through so the feather is an outline and the quill shows.

Design by KameleonForge

A paw print with four toe pads and a deep heel pad, cut 2.3 mm thick so the pads stay proud of the outline instead of blurring into it.

Shown as a render of the printable model, not a photograph.

Design by Slowpoke’s Workshop

A flip-flop outline, 48 x 18 mm and 2 mm thick, with the strap drawn as an open line across the sole and an eyelet at the toe for a hook. Long and narrow, so the pair swings rather than sitting flat against the ear. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by C4UStudio

A mirrored flourish - a curling stem with leaf-shaped tips - cut 2 mm thick, each about 24 x 36 mm with a hole at the end of the stem for a hook. The pair prints flat as one piece and lies along the ear rather than hanging off it. Shown as a render of the printable model, not a photograph.

Design by Vulcain

Two clickers that look like lunch: a bao bun with its pleats, and half an avocado with the stone still in. Each is two printed halves that snap together over a switch, so the whole thing is the button. Pick the one you want - about 1.8" across. Shown as a render, not a photo.

Design by iNkosi3D

Design by HaPeHu

A heart built from two nested outlines, so it reads as a heart from across a room and stays light on the ear.

Shown as a render of the printable model, not a photograph.

Design by Fetter79

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.

Design by kot1199

A volcano model 5.9" across and 3.1" tall, printed as one piece - a desk piece, or the model for a school project on volcanoes. Shown as a render of the printable model, not a photograph.

Design by euro100xx

A hummingbird in flight framed by a teardrop outline: the bird sits inside the frame and joins it at the wing, with the hook tab above. Each is 27 x 41 mm and 2.3 mm thick, so the frame holds its shape rather than sagging, and the pair prints mirrored. Shown as a render of the printable model, not a photograph.

Design by Vulcain

Design by Ettore

Design by Brightbox

Design by mikan

Two five-pointed stars, 35 mm across and 2 mm thick, a hole at the tip of one point for a hook. Printed flat in PLA with no supports, and light enough that the pair is about a gram and a half of plastic. Designed by instintkiller and printed under Creative Commons Attribution 4.0 (CC BY 4.0). The "+ hooks" option arrives with the metal hooks fitted; the plain one is the printed plastic on its own. Shown as a render of the printable model, not a photograph.

Design by instintkiller

A lotus flower built from three rings of petals, the outer ones splayed and the inner ones cupped, so the flower has depth from every angle.

Design by Pistachio

A heart outline with a horse's head drawn inside it in one open cut, 40 x 37 mm and 2 mm thick, with a hole at the top of the heart for a hook. Almost all of it is outline, so it is light on the ear and reads as a horse from across a room rather than only up close. Sold as a pair. Shown as a render of the printable model, not a photograph.

Design by C4UStudio

A cowboy boot with the shaft, pull tabs, heel and stitched sole all standing proud of the outline, so it reads as a boot rather than a silhouette.

Design by D.MacMcAlister

Design by specialman
