Magic Mill III Plus Cyclone Cup

Bought a used grain mill (Magic Mill III Plus) for my wife, it dates to the 80s I think. Interesting model that uses a “jet mill/micronizer” instead of grinding stones. Works great, but was missing one component... I couldn't find replacement parts anywhere but I found some pictures in some online listings and did my best to model off those. Seems to fit ok. 

Edit 9/13/24 - Thickened walls of the cup a bit, tapered even thicker towards the top, and modified the tab locations to better align the triangle/handle in the machine.
