I made this dril chuck key holder for my drill press. A protection shield with a 15x15mm aluminium post, which i don't use (even couldn't my first drilling job because thing was in the way..) I decided to make a drill chuck key holder that could be clamped instead. You can use it as is, or insert 1 or 2 magnets with a 10mm diameter with a little screw to let the key click in its place. Work beautifully! I also made a universal version you could mount virtually anywhereclamp size is exactly 15x15mm. I ended up printing it at 110% for a tiny better fit
