Spray Paint Shaker

This spray paint shaker is tapered to snugly and securely fit various spray paint cans in the neighborhood of 66mm diameter. The bolt hole is made to fit a 5/16" (about 8mm) carriage bolt because I had one laying around. You can use whatever you've got that fits through, just tighten it up with a washer on each side. Alternatively you can download the step file and customize it however you want.

I recommend printing this in PETG, ABS, or the like.

Plop the can in and spin.
