Continuum Arm
Print Profile(0)
Description
There are 3 pegs on every spacing disk for springs to go on top of and a hole through them for fishing line (tendons). The outer diameter of the pegs (inner diameter of the springs + ~0.125 mm) is 5.358 mm and the inner diameter is 2.953 mm. I'd recommend 25lb - 20lb fishing line for the tendons. 15lb - 10lb if you don't have strong servos or stepper motors. The threaded holes in the front of the base are for the M3 screws, the non-threaded holes in the front of the base are for the fishing line tendons to run through, and the beveled holes in the bottom of the base are for the wood screws.
(NOTE: This .3mf is JUST the arm and base)
