Generate a perfectly fitted, 3D-printable case for your Micro:bit Educational Foundation BBC micro:bit V2. Verified 51.6x42mm base dimensions with Above-board for component clearance; below-board for battery pack mating.
Educational board dissipating <300mW. Designed for classroom handling, not thermal-stressed.
Classroom / student use demands impact resistance. PC is the default for durable educational fleets. TPU provides soft-edge protection for drop scenarios. PETG is accessible. PLA is specifically discouraged — it shatters under classroom-level impact.
LED matrix apertures must be aligned precisely with the 5x5 grid — 25 individual light paths matter for readability.
Touch buttons (A/B) and pins 0/1/2 — preserve access for educational exercises.
Edge connector on bottom accepts crocodile clips — do not obstruct.
Onboard accelerometer + compass — maintain 15mm metal-free keepout if magnetic heading is used.
Micro-USB for programming — MUST remain accessible.
