Horn Assembly for older GM cars (Like a 1979 Camaro Z28)

I've seen a lot of these old horn assemblies going for $50 to $100. Most of them have broken tabs. I made this one pretty beefy and would suggest 100% infill. Enjoy!
I deleted the tabs because they break easily. I replaced them with beefy spheres.
the metal cup that this part fits into is 57mm (inner ridge) and 58.5mm for tabs that secure past the ridge. The overall outside diameter (that tucks into the rubber horn button) is 90mm.
I included the Solidworks part file if you need to modify my print or make a remix.
