A single M2 screw is used to keep everything together. Button is reachable via rather big hole. SWD port is usable even if PCB is in case.
Problems:
- Thick fingers are unable to reach the button. This is only a small issue however as the button is used rarely.
- Screw at the bottom is sticking out if head is not very flat.
- Structural integrity not perfect.
Based on Version 1 but with changes:
- Big hole is replaced by smaller one and a small piece of plastic is used as a button.
- Screw is moved to another location
- Bottom wall is thicker so screw head is not sticking out.
