3U rack; shield for Raspberry Pi 3 and 4 series + OLED 128x64

Description

These are the shields for the Raspberry Pi 3 and 4 series. It is part of a project in which I mounted Raspberry Pi's a USB hard-drive and a 5-port switch in a 3U Europac case. These creations are a mix from the original design by SlideBOR in his creation https://www.thingiverse.com/thing:3022136. Since I have some 3U cases I wanted to have shields for it like SlideBOR made. Unfortunately it contained only the STL files. My design is one with a 128x64 pixels OLED screen, the design by SlideBOR is one with 128x32 pixels. I could add additional info, so I had to (re)design something myself in 'infoscreen.py'. I like every aspect of a project, including any programming. So, since the python file didn't really gave me a challenge I went for the shields in SCAD. Everything is here, including the SCAD file, so everyone can change whatever is needed. I am not going to use a switch to halt a Pi for instance. I'm basically using CLI so I go for a proper 'sudo poweroff' over a SSH connection... If you want to have it... you're going to have to add it. For the details on how to connect the LED, the OLED and the switch(es) I suggest you follow the link to the Thingi from SlideBOR. Again, it started with the design from Kapozok (https://www.thingiverse.com/thing:1793758) and SliderBOR https://www.thingiverse.com/thing:3022136. There is one shield left in this project, the HD shield. It will be available soon, also in SCAD format. Warning for people who are actually going to use the SCAD files; I started of in Dutch, I translated the 3B file, but left comments in the 4B file in Dutch... get international ;-) Also look at: https://www.thingiverse.com/thing:4858870
