About this part

Seems to be accurate enough to hold in my car. Unfortunately, the reason I made this was because I broke mine, so I did not have a good example to go off of. Therefore, the measurements are not precisely the same as the OEM bracket. After some tweaking it seems to be a pretty good shape to hold the unit in place. I will update this file with any improvements I make to my own.

Because of the heat of a car's interior, this will need to be printed out of either a heat-resistant filament, or annealed if printed out of PLA. I had success with bed annealing PLA at 70 degrees for 2 hours, and 80 degrees for 2 hours. I printed the part with a large brim, and annealed it while still stuck to the bed, weighed down by a bag of sand. No warpage observed. The part shrunk approximately 1.5% in the X and Y axis, and grew 1% in the Y axis.

Update 7/15: Added reinforcements to top and bottom because the original design flexed too much. Adjusted pin/screw holes for a better fit.
