Raspberry Pi 1B 1U frame

I wanted to use the rack but I only had Pi 1B's and they are wider with the composite port.
The frames are approximately 77.8mm so you can't fit 6 of them in. I didn't feel like designing a spacer and just used extra nuts to center the ones frames that I printed on the rods.
I designed the frame to only need support with the base.
No support on the tray.

The cutout on the back is for the micro usb cord to fit through if you want to use that
