A lid that snaps onto a standard can and seals it up again between sips, and doubles as an opener when you slip it over the tab and tilt. It is the wider, support-free version, and it fits both the slim and the fat cans the designer built it around - European 202 cans, so if yours is a different can it is worth a quick measure. Light sanding on the slots is the only finishing it asks for.

A paw that rides on top of a straw: the straw passes through the middle of it, the paw sits above the lid, and the raised pad and four toes catch the light as the cup moves. It is made for the 10 mm Stanley straws, 3.5" tall by 1.6" across, and it prints in one piece. Shown as a render, not a photo.

A print-in-place bag clip: the hinge prints shut and then works, so there are no pins and nothing to assemble. 3.2" long, 1.2" wide. Shown as a render of the printable model, not a photograph.

A plump bee that clips onto the top of a straw, wings raised and its stripes cut deep enough to read across a table. It suits the 10 mm Stanley straws, is 1.6" by 1.5", and prints in one piece with no supports. Shown as a render, not a photo.

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 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.

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 pair of lips that sits on top of a straw: the straw passes through the middle and the lips ride above the lid, catching the light as the cup moves. It suits the 10 mm Stanley straws, is 3.9" tall by 2.2" across, and prints in one piece. Shown as a render, not a photo.

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.

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.
