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 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.
