Hook clip / clothes pin
thingiverse
Made a clip with a hook (round & square), using rubber bands as the spring. I made it mostly so I can hang a plastic bag to use as a garbage bag. But it can be strong enough to hang a lot of different things if you use a strong enough rubber band. Printed on the side at .24mm at 45% infill with support touching build surface. Edit (2/2/19): Added a non-hook version so that it can be used as a clothes pin / bag clip. I actually like using this as a bag clip more than the wide bag clips I made previously.
