I recently gifted my Ender 3 V2 Octoprint running on a Raspberry Pi 4 and needed a place to attach it to my enclosure. I found a simplistic case and printed it but then needed a way of attaching it to my enclosure, thus this creation was born. 

I used supports for the vents and overhangs on both sides but theoretically would work without them.

Internal dimensions : 93mm L x 29mm W x 70mm H
