I designed this clamp to hold the stock down to the CNC work surface.
All parts are sized to fit with M8 threaded bar.
Warning: the "M8 Bar Cap" is designed to be printed with TPU filament; if printed with PLA the tollerance should be adjusted properly.
Warning: for the "M8 knob" you may want to use a brass M8 insert instead of the plastic thread to improve durability.
