I wanted a little mini version of my e450, so made this!

With this case you should have more than enough room for a Pi, one or two hats, and a 40mm cooling fan! The grated design on the front and 40mm fan on the rear gives plenty of airflow while still looking styleish

Print in two seperate halves that then slide together before being bolted for a secure fit.
This case should be able to comfortably fit a Pi3, Pi4 or Pi5 without issues.
PRT-A uses three M3 heatset inserts to secure the two halves together.
PRT-B uses four M3 heatset inserts inserts to mount the rPi.

Model may be a little scuffed, this was a personal project!
