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.

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.

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.

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.
