LED Ring V3

I have updated the ring and arm model to allow for screws to be inserted from the top down, resulting in a cleaner and more flush appearance for LED support. I have made this model for the 4-way and 5-way modules. Each module only requires 2 M3-16mm screws per arm, totaling 10 screws per 5-way module. The support arm can be placed flat on the build plate without additional support; however, the ring model does require support for the tabs. Using PLA, both models are printed with 80% infill, 60mm/s speed, and 210 degrees for the extruder. (The arm model says it's not manifold, but it printed fine.)
