Generate a perfectly fitted, 3D-printable case for your Arduino Arduino Mega 2560 R3. Verified 101.52x53.3mm base dimensions with Above-board for shield stacking (~10mm/shield).
ATmega2560 dissipates ~100-150mW — no ventilation required.
Large shield-compat board suits PLA for most projects. PETG for environmental resilience. ABS for integration into larger assemblies.
Shield form factor — accommodate 2x18 + 2x36 header stacks. Many Mega shields are taller than Uno shields.
Larger PCB than UNO — mounting holes pattern is similar but not identical; design bosses per Mega spec.
USB Type-B on one short edge — tall receptacle requires clearance for plug.
Barrel jack adjacent to USB — both must be accessible OR one must be blocked deliberately.
4 mounting holes inherited from original Arduino Mega position; asymmetric pattern.
