Tatoo machine (novelty)

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.

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.
