Desigen from scratch with Mini Clamp as reference as i did not like the tread that was used and no good grip of the screw by hand.
Tread used is M6 so some cut on a M6 bolt can be used to clear the tread of the clamp and replaced with bolt if needed. added the same type of rotating part to catch the filament and also added a bigger grov for some of the bigger spols that have a rib.
