Roller Massager

The handle utilizes (6) Rollers.

It uses an M3x50mm screw as an axle and is secured with an M3 nut. The screw is from here:

The screw and nut is recessed into the handle on both ends so no metal sticks out.

Each of the (6) rollers are 6mm thick and 30mm in diameter.

Be careful to not hurt yourself or anyone else as the rollers spikes may be sharp. My roller spikes were not sharp in reality after printing though. Keep it away from long hair.

I'm happy with how it came out.

Enjoy!

Update 11/08/2021:

The response was positive so I decided to add a step file and my Fusion 360 project file. I designed it so handle dimensions could be modified symmetrically by editing the dimensions shown on a Fusion 360 sketch.

Have fun!
