Hi and many thanks for this great project.
I am on the way to build it and printed all parts with PLA. The looks good but there is way to much friction even if i remove the brake on the opposite side of the servo. Sometimes there is too much force necessary for the servo (it stucks) and sometimes the arm is locked in the pushed position so that the spring cant push it back.
Anybody with hints how to make it more reliable?
Many Thanks,
Tom
