Summary

Chip clip with cam locking mechanism. I recommend using PET-G instead of PLA to the clip body because PETG seems to retain "springiness" better. The spring mechanism and cam mechanism are printed in-place. After printing, gently work the arm back and forth to free the mechanism!

Update 8/26/2021.

1. Changed the cam design to grip more tightly and to lock more securely.
2. Added a print-in-place single piece version.

Update 12/2/2022

1. Changed the cam design to add more teeth and grip
2. Revised cam and arm design to improve click in place and improve ergonomics.
3. Removed old design with pins.
