Vortex Mixer Chucks for Model Acrylic Paints

I bought a Four E's vortex mixer and noticed the rubber cap came off. I then saw that there was a spot for an M3 screw, and designed up some simple chucks to hold onto paint bottles. Simple print in place design for your paint brand. I use some rubber bands across the tops to hold thinner bottles.

Currently Designed:

• Dropper Bottle support up to 25mm thick
• GW pots 
  • I've had a few issues with these sneaking out, so I wrap a couple rubber bands on themselves and lay them across the top to keep them down.
• Monument Hobbies Pro Acryl
• Liquitex Ink
• Kimera “the color” brand
  • These ones are imbalanced and shouldn't be used for long otherwise they tear themselves apart. I'm going to be working on a redesign, but for now this is what I have.

Future Designs:

• Kimera v2
  • I would like to see if giving it a bit more girth would balance it better
• Dropper bottles for thinner and thicker bottles
  • No two amazon purchases are the same. I bought a certain set of dropper bottles and my buddy did too. We both got different thickness bottles.
  • For now using the rubber bands for the thinner ones works well.
• A desk attachment
  • at full speed this thing walks around my desk. I want to find a way to keep it in place.
• Silly addons
  • like the monster hunter wiggler head.
