I made this simple mount to simply mount my pi onto the wall. The spacers are in case your screws go through the plate, so they don't put more holes in the wall. I forgot about the SD card slot and the model in the picture doesn't have a cutout but I added one in the uploaded model.
It's designed for M2's not M2.5's. I designed the mounting holes for #6x1/2" wood screws, you can use M3's or the same wood screws for the fan.
The author marked this model as their own original creation.
