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.

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 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 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

An inner cone passes right through an outer one and neither of them comes apart - that is the whole trick, and it prints as a single piece. Roll it in your hands and the two bodies slide past each other, which is the part that keeps fingers busy. Printed in two colours the cones separate in the eye and the pass-through reads as impossible; printed in one it looks like a solid cone until it moves. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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 little cauldron with a lid full of bubbles, sized to sit over a battery tea light: the light comes up through the bubbles and the whole thing glows. It prints in two parts, the cauldron and its top, so the top can be a different colour from the pot - the designer printed the tops in plain white and let the tea light do the colour. About 70 to 77 mm tall once the two parts are together. Battery tea light only, never a real flame. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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

A clicker keychain with four buttons that press and click, printed in place so nothing needs assembling. Shown as a render, not a photo.

Design by Print3DFamilyFidgets

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.

Design by Cardboard Junkie

Four Jeep charms, each a different model cut in relief and each with a hole at the top for a keyring or a chain. Pick the one you want - they print flat with no supports and measure about 2.4" by 2.4". Shown as a render, not a photo.

Design by dominator334

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

A low-poly heart, faceted like cut stone: the low-poly build keeps it light and lets it catch the light along the facets, and it stands on its own on a shelf. 3.4" wide, printed in one piece. Shown as a render, not a photo.

Design by Creaitivity Studio

A vase with a wave running up its wall - a single spiralling surface, so the ridges catch the light differently as you walk past it. 180 mm tall, and shaped for dried flowers, pampas, feathers, or for nothing at all in a bare corner. It wants a dry arrangement rather than water. Print it in a silk or a matte filament and the waves do the rest of the work. 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

Mark the shark as a keychain or as a necklace charm - the same shark in two fittings, one with a ring hole and one sized for a chain. It prints flat with no supports, about 2.4" long. Shown as a render, not a photo.

A little bear holding a heart, printed in one piece with the heart standing proud of its chest. 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.

A coffee cup for a keyring, complete with a lid and a sleeve, small enough to disappear in a pocket and clear enough in shape to read at a glance. 0.8" across and printed in one piece. Shown as a render, not a photo.

Design by Tuscarora Tech

One little ghost, three sizes of it: Small is 35 mm tall, Medium 45 mm and Large 64 mm, so a shelf can gather a few rather than carry a loner. Each prints as a rounded little spectre with a friendly face and no supports. Every ghost is its own object on the plate, so no multi-colour printer is needed - print them in different colours and they arrive as a set. The small one disappears into a bowl by the door; the large still fits in a hand. The picture is a render of the printable model - real photographs of the print go up once the first one is made.

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.

Six dog charms with a bit more detail in them - a bone, a ball and a few breeds, each cut in relief. Pick the one you want: every charm has a hole at the top for a keyring or a chain, prints flat, and measures about 2" by 2.4". Shown as a render, not a photo.

A cat curled into a charm, cut as a flat silhouette with a hole at the top for a keyring or a chain. Shown as a render, not a photo.

Design by dominator334

A tall vase with a drop falling through its wall, and the tray that holds it: the designer made it for a single stem or a bundle of dried grass, and the tray catches whatever you drop in it, which is where the mindfulness comes in. Printed as two pieces - the vase and its holder - so you can use them together as an arrangement or keep the tray on a desk for rings, keys and incense. Standing 24 cm, it wants a shelf with headroom or the middle of a table. 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

A DAD heart gyro fidget: a heart with DAD cut through it, mounted so it spins in the frame when you flick it. 1.8" by 2.2", printed in one piece with the pin already in place. Shown as a render, not a photo.

Design by LangHjornArt

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.

Design by dominator334

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.

Design by CreaitivityStudio

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.

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

A frog that jumps: press its back and it springs off the table, and the pond bowl catches it. Pick the frog on its own or the bowl with it - the bowl is 5" across, and three frogs fit on one plate if you want a set. Shown as a render, not a photo.
