Eccentric paint spray can shaker/mixer for your drill

This is a convenient paint shaker for spray cans. It consists of a hollow cylinder with an elongated hole at the bottom. There are two sizes availabe: 55mm (works for smaller cans like those from Edding) and 68mm (works for most other cans I had at hand).

The internal diameter (55mm or 68mm) is deliberately oversized, so that you can fit some kind of paper or fabric (I use shop towels) in there to hold it firmly in place. By doing this you can shake it in any direction, even upside down.

The elongated hole at the bottom is sized to 10mm in both cases. It's meant to take an M8 bolt, that you can use to attach it to your drill. Make sure to use some washers, since the hole is quite big for an M8. Also keep in mind that this is plastic, don't torque it too hard. By choosing different positions for the M8 bolt you can choose different amounts of eccentricity. More eccentricity might shake the can more, but also means more vibration in the drill and more stress on the printed part.
To be honest while designing I had no idea what amount of eccentricity is good, so I just made it adjustable. Putting the bolt at the most inside point of the elongated hole gives you no eccentricity.

How I Designed This

I created this because I needed it for a project. I looked around on printables and elsewhere and couldn't find something according to my needs. But when I typed it into Google the very first thing that came up is a brilliant video by Adam Savage on his Tested Youtube channel. In the video he showed the inspiration for the printable that I've created.

If you don't already know this channel I can't reccommend it enough. He is a master prop builder and maker and I learn a lot from his (also entertaining!) videos. Here's the video in question:
