Raspberry Pi Stacking Mount

The original version by MechJack was very slightly undersized for me and I couldn't get it properly sized even after printing a few at different scales.

This version is sized exactly for the Pi 4, but works with no issue for a Pi 3B that I have.

2020/03/21, Update 1: Added a label piece. I just write on it with a contrasting sharpie, but I could see putting tape on it first to provide a better writing surface or just emboss text on the flat side with the modeling software of your choice.
