This removable arm is a modified version of the original arm designed by https://www.thingiverse.com/DrazzticAction/about (https://www.thingiverse.com/thing:773666). The arm design required the purchase of additional metal parts from a third party company. Unsatisfied with that course of action, I designed this arm to use a close-fitting square peg and socket to lock the pieces together. I recommend using super glue to permanently connect the two pieces. The smaller portion of the arm is a modified version of the model by https://www.thingiverse.com/garfong/about(https://www.thingiverse.com/thing:876823) This is the first model I've uploaded. Please feel free to give feedback! each piece is designed to be printed alone. The larger of the two will need to be rotated diagonally to print on a lulzbot mini bed. after they are printed, simply superglue them together and insert into the removable arm slot (https://www.thingiverse.com/thing:756064)
