Small Rubber Band Spring Clamp
I designed these small clamps to help with plastic modeling, specifically, this, which is a really neat model: https://www.thingiverse.com/thing:998240. I'm pretty happy with how they came out.
There are two files, a Pivot, and a Leaf, which must be printed twice.
This uses skinny rubber bands.
***UPDATE
I remixed my own junk!
I created a pointy pair of leaves, and they're mirror image, so one file, one print. They're not symmetrical so they're easy to print. Uses the same Pivot.
