Two layered Christmas trees, 33 mm tall, each with a loop at the top for a hook - a few flat layers stacked into a tree, so they read as a tree from the front and none of it is a support to remove. 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.

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.

A reading guide that frames one line at a time so the page cannot swim: 5.1" x 1.4", 1.4 mm thick, light enough to leave in a book. Kept for kids learning to read, and for anyone whose attention slides down a full page. Shown as a render of the printable model, not a photograph.

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.

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.

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.

A heart that sits on top of a straw, wide and low, catching the light as the cup moves. Shown as a render, not a photo.

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.

Wet gloves dry upside down on six tapered, vented posts, over a 4x10 inch floor vent. A glove's cuff slides over a post so warm air from the register goes up through the post and through the glove, drying the inside as well as the out - which is the part that stays wet. The tray is a colander: a lip catches a dribble of water, and a grid of drain holes lets the air up and the water down, and each post drains through its own cup. Bottles and cups fit the posts just as the old stand's did. Sized to sit inside a 4 by 10 inch register, printed in one piece with no supports and nothing to assemble. The photo is a render of the printable model - real photos of the print go up once the first batch comes off the printer.

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 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 fold-over bag clip in one piece, with nothing to assemble: two slim bars on a round hinge, and a hook at the far end that shuts them. Roll the bag's neck over, slide it in side-on between the bars, and press the hook home - the knob at the end of the curl rides over the upper bar's tip and drops into the groove cut behind it, so the clip is held shut by the hook and not by the moulding. Flex the curl back off the tip and it opens again. The hinge is a disc with a hole through it, so the clip hangs on a keyring or a cup hook when it is not on a bag. It prints flat as a single piece with no supports, and PLA holds fine while 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 batch comes off the printer.

A dragon in a coiled pose, wings half-open and tail curling round to its head - a display piece rather than a toy. 9.5" across and the biggest thing on the shelf, printed in one piece. Shown as a render, not a photo.

A bag clip shaped like a cat, with a spring jaw that holds a chip bag or a coffee pouch shut. 1.6" across, printed in place in one piece - the hinge comes off the plate already working. Shown as a render, not a photo.

A cap that turns a jar into a fruit washer: fill it, shake, and the water spins the berries clean instead of bruising them. The cap and its inner piece print together in one go - size L fits a standard wide jar. Shown as a render, not a photo.

A Christmas cookie stamp and its matching cutter: press the stamp into the dough and the outline cuts clean around it, so the icing has a line to follow. 3.1" across, printed as two pieces - stamp and cutter. Shown as a render, not a photo.
