About this 3D model

I tried to build classic tattoo printing machines. They worked very well, so I decided to create this 3d printed model. I used the Software rhinoceros 5. There are two 3d printed pieces: the grip and the frame. The device works pretty good. I tattooed about 10 people with this machine, no problems Get the other parts from: http://www.luckysupply.com/tattoo-machine-parts
