Replacement part for Planet Waves guitar capo

This is a replacement part (circled in the picture) for the Planet Waves guitar capo. The original part tends to crack and split along the grooved section, and cannot be purchased separately - rendering this very nice capo unusable.

Print with solid infill for best results. It is a small part so the extra material is negligable. I've printed in PLA and will update about its durability if and when it breaks.
