I merged the Prusa MK3S-style IR filament sensor portion of the second design listed above into the first, and cleaned things up a bit. Additionally I made some alterations to the bolt holes and overhangs to make it more FDM friendly and reduce the need for supports.
I consider it a WIP as I am still working some bugs out regarding the filament sensor, but I think those issues are mostly firmware related at this point and I'd like to work on the wire management a bit more, but so far the test prints I've made seem pretty good.
I took the gears, bearings and such from a BMG extruder I was already using on my Ender 3 Pro and I used these sensor parts from Amazon: https://www.amazon.com/gp/product/B07PYQWGK1

Supports will be needed for the Fan Mount, the Filament Sensor portion of the Front piece and are recommended, though not essential under the overhanging bits of the back where the motor goes in.
I used Painted-on supports in PrusaSlicer 2.3 to limit the amount of supports to the bare minimum.
Prusa recommends printing the R3 fan shroud in ABS.
