This is a case for Rock Pi X (model B) with heatsink.
The idea came from: Rock Pi 4 (with heatsink) case (https://www.thingiverse.com/thing:3499190)
Use supports for Bottom.stl
No special settings needed for Top.stl or Button.stl
You need one M3x4 screw to fix the buttom from falling out (see images above).
Use the step files to remix it.
Have fun!
