A vortex mixer for miniature paints. Fits Vallejo paint bottles. Requires a 22 mm OD, 8mm ID, 7mm thick bearing.
A second cup was added that should fit citadel paint pots.
Let me know what you think!
Amazon Basics / E-flex PETG / TPU
Print the cup bearing side up. No supports needed, but use a brim to keep it stuck to the build plate.
Print the drill base using concentric circle layers and the temporary base (integral brim) should remove easily.
I printed the cup in TPU and the drill / bearing base in PETG.
