Pi Plate (simple raspberry pi 4 mount) - modified

Tweaked the original Pi Plate model, as I needed something just a touch different--specifically, mounting to M5 t-nuts in 2020 extrusion rails.  However, the Pi Plate provided for a good reference/starting point (sized right for the Pi4, standoffs already in place and sized appropriately for the Pi4 screws, etc.).
Squared off and solidified the plate itself, added chamfering to the Pi mounting holes (back side of the plate), made the upper mounting holes sized to fit M5 screws, and chamfered the mounting screw holes.  Also added a slight chamfer along the outward facing side of the plate for a cleaner look that matched other parts already printed for my enclosure.

FYI - in attached photo of my print, the standoffs have been modified post-print (trimmed with an Xacto knife) due to the fact I use an minimal aluminum case for my Pi, and the shape of the case's screw holes interfered with the round standoffs on the modded Pi Plate).
