Raspberry Pi 5 multiple mount

I used screw m2.5 8mm and 14mm to conect the raspberry pi the the towers and Braas insert nut for everything I built it to support the m.2 SSD on the top. to build a tower similar to my tower is necessary build the top tower first. in my case for instance I builded the SSD case after the middle Raspberry and after the raspberry on the bottom.
