Microbit Case with hinge & using paper clip to lock

thingiverse

I decided to modify the original design because I couldn't find a small screw that was readily available in my city. To overcome this challenge, I made four significant changes: (1) I split the case into two halves instead of a single piece and a separate plate; (2) I added a hinge to make it easier to open and close the device; (3) I included a side slit that allows me to insert a paper clip as a makeshift lock; and (4) I increased the height of the case by 1mm to prevent accidental button presses.
