Wire Race 150mm w/ heatset inserts

This is a remix of https://www.thingiverse.com/thing:4909602. I have modified it to use the 5x4x3 Heatset Inserts used in the Voron builds. I made the base 0.5mm thicker so you can use an M3x6 screw to assemble it with.

Added files for 122mm length wire race that works better for the Voron Switchwire.
