A small case to hold up to 3 different single board computers / microcontrollers.
Each board is attached to a carrier that slides into the case. It was designed to house all of my home automation gear - at the time this was a RPI3b running HomeBridge, RPI4 running Home Assistant and an Arduino Mega2560 configured as an RFLINK for 433Mhz devices.
It has since evolved to remove the arduino and add a sonoff RF Bridge (the RFLINK couldn't learn some RF codes that control some ceiling fans I have) and to add a Zigbee gateway; this has meant designing a new carrier for the bridge, and a new lid to accomodate the zigbee USB stick that sticks out of the top thanks to a right hand USB adaptor plugged in to the PI4
Print what you need - the file names are descriptive so you should find what you want, and I've included STEP files of everything should you want or need to tinker for your circumstances.
Everything prints without supports, if you orient the parts correctly - it should be obvious which side is down to the print bed.
The feet are glued in to the bottom of the case
The antenna mount is glued into the lid in the same way, if you need it
