Rotary Tattoo Machine

This is an incomplete rotary tattoo machine for a new robotic arm platform I've been working on. I'll be modeling different pushrods and cams for different stroke lengths but it currently sits at 12.5mm and is not suitable for tattooing. Fits normal dc motors with 20mm bodies and 8mm tubes. The next update will have corrected strokes, as well as a guide rail in the body to keep the needle centered, and a microstepper injector to keep ink flowing at a good rate. The point of this hand is to produce high quality, accurate machines with all 3D printed parts for interchangeable machine heads
