A tiny and low cost protector for the microbit V2/V2.2 I use in robotics classes.
Contacts remain exposed for sliding into pin breakout board.
Assembly: Start by sliding in the buttons and then push the snaps until click.
For disassembly pull aside the tiny flaps until snap releases. Take care not to over-stress the buttons.
Printing: Use minimal support for the small overhangs.
