Alan Here: I did break up the signal into parts; never used .step files though perhaps I should?
Hi Alan, I like the part, but the one on the server is a single STL with all the pieces floating in it. The biggest difference between the STL and STEP is that the STL is basically defines the vertices and surfaces and doesn’t understand the actual geometry , not something that can be edited (easily). A STEP file will define the actual geometry, how it relates and allow it to be pulled apart, remixed, or whatever in programs like Fusion 360 or whatever. Easier than supplying the actual CAD file.
