My goal was to mix two component polyurethane precisely, but turned out it was a bit more than just pushing the two part together trough a mixing nozzle. Anyways, here's the assembled version. I'll add the parts separately, and will write a larger instruction for it.
I'm no engineer, parts was modelled using corel draw and 3sd max :)

Materials and methods

I recommend using PLA for strength. The outer shell was made from 18mm MDF. The bearings are simple 608. The motor is a n1ma17, driver by a DRV8825
