Paint can shaker/mixer for hand drill

This is a simple shaker/mixer that attaches to your hand drill (corded/cordless) to drastically speed up the time it takes to mixing of a can of spray paint. No longer do you have to shake the can manually for a minute or more. I've managed to restore a can of years-old primer paint within a minute using this. 

Includes a small wedge for keeping the can in place while being mixed, and the wedge is stored in a small opening in the main part so you don't lose it. Designed for a standard 66mm diameter can, although it could easily be remixed for different sizes - I have included the Fusion360 source files for both parts.

Print design, insert the bolt with the bolt head captured in the bottom of the mixer and use a washer & nut to secure. The design has a 8mm hole & a recess for a 13mm across-the-flat bolt head to suit either M8 or 5/16" bolt.
