Rubber Band Clamp

A good friend designed this and agreed to share. He made it for his kids so they would stop stealing his spring clamps to hold blankets to chairs and such for kid fort purposes.

It’s a simple clamp that could be modified for specific needs. It utilizes rubber bands for tension which are much more versatile (need more tension? use more/thicker rubber bands!) and much cheaper than springs.

This device requires basic 3D printing skills, and minimal assembly

The design is meant to be print in place, or all printed at one time. After it prints, wrap rubber bands around it to provide tension. The design is meant to be print in place, or all printed at one time. For example, scaling the .stl file to 60% works well with #8 – 3/4 inch long bolts. You’ll need 3 bolts and 3 nuts. Put the bolts in place before you snap the different pieces apart.
