Description

PDF

I was looking for a Pi5 case that used the Noctua A4 5v fan and came across the original as a Pi4 model. I've modified as in the description as I wanted to be able to use for multiple models. 

  • Objects will need to be reoriented correctly 
  • %35 infill
  • PLA
  • brim on the bracket help but not necessary
  • No supports required

The following screw are required:

  1. M2.5 screws for screwing the board to the bracket
  2. M2.5 screws for the front plate
  3. M3 screws for the rear filter plate
  4. Original fan-mounting screws that came with the fan for… the fan

Changes:
Revised to be more modular - changed the case to have an interchangeable front plate depending on Pi version

  • Added brackets for Pi3b/Pi5
  • Created front plates for Pi4b and Pi3b/Pi5
  • Changed wiring passthrough to arch instead of triangle
  • Added notch in backet so it will slide in all the way
  • Added fillets for standoffs for a bit better support
  • removed rib as it's not necessary
