8mm Rod Friction Clamp

This model is a bit unrefined, it's actually the first thing I've made, so don't expect perfection. This was designed to screw to a surface and accept a 8mm or 5/16" rod and with a screw and nut apply varying amounts of friction to the rod. All screw holes are for 3mm screws.

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/aB5nLmGhizT
