Raspberry Pi 4 1U rack-mount bracket for 10" switch

To save my rack size, I have created an enclosure, that fits two Raspberry PI computers next to 10” switch, replacing standard brackets/adapters.
This one fits my TP-Link TL-SG1024D switch replacing original brackets and fitting it’s screws. Please find screwing diagram in photos.
Raspberries are cooled with 10mm fan mounted in the rear, enforcing air flow. I recoment installing at least one fan, as the switch has cooling vents on the side.
I have used z standard hat to connect power. I’m using IRF9540N transistor to protect RPI from reverse power connection.

Printing
• You need one bracket and one ear
• No support needed during printing, unless you need perfect bridges
• For better durability, I have printed with 60% infill
• Original design was ready to be mounted on left side of the switch. To have left version, simply mirror the part in your slicer
• Printed with PLA on my
