Ender 3 under screen raspberry pi 3b+ case

Hi all.

Inspiration for this project was Raspberry pi case designed by Hesi-Re ( https://www.thingiverse.com/thing:3700643 ) because I have fitted in my Ender 3 drawers designed by DWS_design ( https://www.thingiverse.com/thing:3416444 ) none of the cases doesn't fit my requirements. I'm powering my RPi using a step-down buck converter ( https://www.amazon.co.uk/LM2596-Converter-3-0-40V-1-5-35V-Supply/dp/B01GJ0SC2C ) via GPIO pins and also I wanted to be able to fit 40mm x 20mm silent fan on the top of RPi.

One afternoon after I've designed this case and maybe anybody wanted to use this.
