Ender 3 pibox psu replacement

I wanted to power my rpi 3B+ from the same power supply as my ender 3 v2. I copied the original ender 3 style by making the case to mount on the back right rail where the old ender 3 psu was at.

My setup uses 2 5v fans (4010 and 3010), 3 buck converters LM2596 DC-DC (standoffs printed on design, a rpi 3 B+ but a rpi 4 uses the same footprint.

Also, in the background of the photos I modded my ender to have a z belt drive system by kevinaksam (https://github.com/kevinakasam/BeltDrivenEnder3)
