These C clips are designed to clamp onto 8MM threaded rod. These can replace nuts in a lot of situations. They clamp very well, do not slid on the rod, don't rotate easily, and are easy to add and remove.

I designed these for my spool & mount system (not yet uploaded) to replace the tedium of adding/removing nuts on long lengths of threaded rod.

Instructions

Print and clip!

Due to their small size, I recommend printing them in batches so they have enough time to cool between layers.
