Vortex Mixer Paint Shaker for Drill - Vallejo/Army Painter/etc Bottles

thingiverse

Took inspiration from this Vortex Mixer and modified its parts to fit my hand held drill instead to mix my miniature paints, vallejo/citadel/army painter/etc. https://www.thingiverse.com/thing:534894 This requires two hands. One to hold the drill, the other to hold the bottle while you push it on the mixer. It will not spin the bottle as you hold it firmly, rather oscillates it like a vortex mixer. I recommend some lubrication where the slip fittings are, running too long will soften the PLA due to friction. Let it cool, restart. Someone could modify this to include ball bearings instead of PLA on PLA slip fit. Simple and is working great for me. I prefer not to shake my paint bottles as it introduces too much foam/air mixing and spewing out with bubbles. Update: Added the slightly larger_bigger coupler that increases the 'vibration' and enlarges the portion that fits in the drill chuck. Note: I've had breaks in the weak points using this too aggressively, expect to print extras over time. Don't expect too much out of PLA here.
