About this 3D model
I could not find my capo and I couldn't find a spring so I made this. You'll need: - a thin sheet of cork or rubber. - 1.25" 4-40 screw - 0.5" 4-40 screw - 0.25" 4-40 screw - 4-40 nuts and washers - heat shrink tubing I cut out a small strip of cork to fit in the small pocket of the 'capo top' part and held it in place with hot glue. I covered the 'capo clamp' with heat shrink tubing. Assemble as shown in the pictures. The 0.25" 4-40 screw is screwed into the 'capo top' for the clamping screw to push on. I printed this with 3 perimeters and 25% infill and it is plenty strong in PLA. Enjoy.
