This is the current ear piece

I still haven't changed the nut for the front wedge of the ear piece, as I noticed more pressing things to alter.

This is a screencap

This is my current model

These changes need to be done

• Triangles on the back edge need to be larger (I'd assumed they were the same size as the triangle on the frame of the real visor bu they're not)
• The screws holding the "camera mount" piece are smaller than M4. Most likely M3
• The vent plate is taller and/or more narrow, not like sided square
• The block with circles is overall smaller and has a proportinally smaller inner ring
• The edge of the back end chamfer lines up with the corner of the large body on the conduit
• Nut needs to be larger, also holes in plate are missing and the plate needs to be more angled so that it disappears in the front (dug into ear piece originally)
• top-back edge chamfers need to be larger and/or different angle
• Front chamfer toward visor needs to be non-linear, I had it somewhat like that but changed it back because it didn't seem quite right then. I'll just have to change it again. It probably needs to be cut with a complex curve surface to get just right. 

The V-cut at the front top of the arc also needs a chamfer.
