Minimal PI 3+ Holder for system32

I never could find a proper solution to mount my PI and PI cam in my build enclosure, which is a modified IKEA kitchen cabinet with 'system32' holes.
I designed this mount as an intermediate mounting, pending an addon design.
This design is very minimalistic and requires few filament, and is easy to print, and provides full access to the entire PI.
It can be mounted into the system32 holes by plugs that can be fixed in place by small woodscrews (3.9mm)

I also designed a modular system32 PI Cam holder see (Modular PI Cam housing with system32 support)
