Testors Paint Mixer

I often have small bottles of paint that need mixing - especially if they haven't been used for a long time. Shaking by hand works to a degree, but I have found that it isn't efficient and takes a long time to mix paint that has settled.

So I went thru several variations of 3d printed blades. At first I sized them to thread onto a 6/32 long bolt but then I realized I could just print the shaft and blade at the same time. I settled on a 3 blade fan with dimensions that are sturdy and yet not so beefy it can't fit into a new bottle.

Sorry I couldn't take photo in use - I need two hands to hold the bottle and drill at the same time.
