Replacement arms of glasses

This is the replacement part of my ESPRINT glasses. Due to the ageing effect, the rubber portion of the arms were breaking into pieces. Therefore, I take a picture from the damaged arm and then recreate the similar replacement arm with PLA.

Rev04 in 2019 is designed after the damage of Rev03 since 2018. The edges are made it round for easy of insertion. LHS or RHS of arm can be printed with the mirror function of Cura.

Hints and tips:
1. Make sure the size of void for inserting steel pin
