Sun Glass Arm, Left Hand side

pinshape

Summary I've lost count of how many sunnies I've had to toss because a small piece of broken plastic ruined them. That's all over now. This design is for the left hand side. Instructions I printed the arm using PLA, and when it was done, I submerged it in hot water, just off boiling point, for about 30 seconds. Once removed, you can hold the arm in your hands and adjust its shape to get the desired curves.
