Support for 2 x Raspberry Pi's, switch, SSD and fans.

For my assembly, I used:

• 2 x Raspberry Pi 4s in GeeekPi Acrylic case (https://www.amazon.com/GeeekPi-Acrylic-Raspberry-Cooling-Heatsinks/dp/B07TXSQ47L)
• D-Link DGS-105 5 port gigabit switch (https://www.amazon.com/D-Link-Gigabit-Unmanaged-Desktop-DGS-105/dp/B000BC7QMM)
• Samsung T7 1TB SSD (https://www.amazon.com/dp/B0874XN4D8/)
• 2 x GeeekPi 40mm LED fans (https://www.amazon.com/GeeekPi-Raspberry-40x40x10mm-Brushless-Radiator/dp/B084RCBSBX)

Everything fits, although the switch is a little bit of an interference fit. I manged to get it in, but it was tight! It might be wise to increase the opening by ~0.5mm in height and width.

I designed it in sketchup, and have included the skp file for adjustment to your own hardware.
