Summary

Remixed some nice Raspberry Pi holders I found here on Thingiverse and created a base and a PSU holder that fit my project.

I created some loose stop blocks just to keep the distance between the Pi's and some tight ones that goes on the ends. They are pretty tight and can be hard to slide into the frame correctly. But once in they lock down the Pi's really well.
