Vortex Cup Ball Stem

Columbia Coatings offers an array of products for powder coat systems. Several of their items needed modifications and improvements for durability, performance and convenience. 

I designed these from scratch in Fusion 360, and ported them to Blender for final touches. Customer(s) have reported this ball stem works better than the bullet stem. 

Please report any difference from existing items provided by Columbia Coatings. 

The intent is to increase the ecosystem of parts available for existing powdercoat systems.
