First attempt to create a basic material clamp for my new CNC which will be operational soon. This clamp is designed to work with either a 1/4"-20 or 8mm bolt and a T-track embedded in the worktable. At the moment I will use a storebought 1/4"-20 knob but might design a printed know with embedded nut as well. First this design and the material needs to be tested to be strong enough.
