This is a snap-action clasp that locks onto a round rod.

This is meant to be a base object: you remix it (union) with something you want to attach to the rod (or attach the rod to). For example if you attach something to the rods on a 3D printer, or want to quick-release a rod (spool holder?) etc.

The design is parametric (open in Customizer or OpenSCAD) but for convenience a few pre-defined designs are included: 8, 10 and 12mm.

It prints in one piece without supports and requires no additional parts. The clasp is captive (it moves but doesn't fall off). https://youtu.be/-0oLQF7g45M

Enjoy remixing!
