Mixing up silicone and resin for molds was getting tiring and sometimes difficult when it was a lot. So I designed this up for an easy attachment to my drill.

Note that this will likely add more air to your mixture, so it's best to use this if you have a vacuum chamber or pressure pot. The way this spins though is with the side of the mixing stick, so it's moving smaller amounts, in a circular path, so it should be more of a swirl reducing the amount of air bubbles.

This is designed to connect with a ¼" metal rod (I used aluminum), 2 M3 brass inserts, and an M3 thumbscrew for easily connecting/disconnecting.
