Sharpie Holder 20mm

cults3d

This is a spring loaded sharpie holder, super simple. I have a clamp already that will hold 20mm items. I had a 1/2in x 2in spring which the wire diameter measured .03in that the sharpie would snug into, so I designed this around that spring and to fit in my 20mm clamp for my CNC router table. There are steps inside to captivate the spring and still allow it to compress and allow the sharpie to push through.
