Use flush cutters to cut out a piece of the “Cover” that presses against the SD Card. When modelling this i did not account for the SD Card protuding, so the cover will press against it and that can break the SD Card Slot.

I'm usin an Orange Pi 3B, but should fit the Raspberry Pi 3B too since they are the same shape.
This was my first try making snap fits on Fusion. They came out a little loose but worked out just fine. Although if I'm ever reprinting this I'd remodel those.
I also forgot to add an opening in the back for connecting my ADXL345 sensor
I'm providing the .step file if you want to make any changes to the model.
The author marked this model as their own original creation.
