Tatoo machine (novelty)

thingiverse

Mini tattoo machine thing. I cut a ball point pen and used its spring to create a tattoo machine. The motor spins a cam which drives the pen. Video of final assembly. If you are interested in the led goggles from the video the cad models are also on my thingiverse page. https://youtube.com/shorts/a1S8YZDyWnM?feature=share The motor I used came from an elegoo arduino starter kit. Its listed as 130 DC motor. The bubble grip handle is a press fit and will not come off easily once you get it in place. I used vice grips and a hammer just to get it in place. This resulted in minor marring of the surface which I hid with modpodge and paint.
