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.Other necessary parts:M8 threaded steel barM8 washerT-track nut/bolt3D printing settings:- Filament: PLA- Infill density: 50%- Layer eight 0.3 mm- Shells: 4- Bed positioning and supports: see attached images
