Redid the top Brackets in order to use M3 8mm Hexagon socket head cab screws instead of the Counter-sunk screws originally needed. The "Shallow" one is the final version and indicates the m3 Hexagon socket heads are totally flush with the top of the bracket, when tightened down.
Same goes for the M5 version. Why the change:
I bought the 10mm m3 "flat head" screws from the BOM, but they simply weren't long enough and I couldn't find any just a tad longer.
I believe jasonatepaint changed his models a bit, or maybe the BOM.I recommend printing these with 100% infill as you really want your corners being totally rigid, and you also do not want your screws to sink in (more than they absoluely need to), when tighening them. I printed with 0.2 layer height and 100% infill. Print it with the guides facing upwards.
