BPI-SM10 metal enclosure (copy)

A parametric plastic enclosure for Banana Pi BPI-SM10 carrier boards (103 × 90.5 mm), designed for FDM 3D printing in PLA. The base tray holds 1–4 boards side by side with user-fitted M3 standoffs through drilled holes in the floor, while a separate lid clamps down with M3 self-tapping screws into corner bosses. Both pieces feature adjustable ventilation slot grills in the walls and lid, an I/O cutout per board on the front for power/display/USB connectors, and optional reinforcement including an inner lip for lid location and a stiffening ridge.
