raspberry pi casing - no screws, cluster ready

housing without screws, cluster ready design, compatible with:
- raspberry pi
- rock64
- other boards with dimensions and screw holes size/location same as in raspberry pi
Optimized for 3d printing, tested with ABS and Prusa like printer.

I will share complete design - rack 19' cluster housing for 120 hot swap capable compute units, redundant PSU, control unit and other.

This design is inspired by HPE Moonshot servers, keeps compatibility with original Moonshot 1500 chassis manager software API and command line interface (as much is possible).

Finished design should be enterprise ready small arm server farm/cluster solution with low entry cost, large selection of compute hardware (arm boards), network hardware (switch/router) under unified managememt.

I admire HPE Moonshot idea. Those devices are extraordinary feat of engineering and innovation, sadly as many other corporate products entire line fall stagnant.
This work follows the spirit (as I understand it) of
