Commutator Balance Arm and Collars
thingiverse
Commutator balance arm and collars for optical neuroscience techniques (e.g., fiber photometry, optogenetics) Provides two axes of rotation in additional to vertical movement to enable minimally restricted tether movement. RJ_1x1_collar was designed to use with the Thorlabs 1x1 rotary joint, and RJ_1x2_collar with the Thorlabs 1x2 rotary joint splitter. ### Print: - DO NOT print with support, as each collar has two moving pieces that will need to be separate and able to move freely. ### Assembly: - The inner ring has screw holes for a M2.5 hex socket screw and some room for an optional M2.5 nut for extra security, if self-tap fails. ### Updates:
