This case is designed for an Orange Pi Zero 2W. It has screw holes for M3x6 screws and M3 T-Nuts to allow mounting onto a 4040 or 2040 extrusion. The case requires 4 M2x16 screws and 4 M4 nuts. The top case has holes for adding heatsinks to the main chips.
Future iterations will use M3 screws to mount the Orange Pi to the case. The M2 screws have some play which won't hurt anything, but it is a little looser than I'd prefer.
