Screw-lid enclosure for an 80 x 50 mm PCB
A general purpose electronics box for a custom 80 x 50 mm circuit board, with four corner posts, a screw-down lid and blank walls you can specify openings in up front. The cavity is 82 x 52 mm for 1 mm of clearance, walls are 2.5 mm, and the lid seats on a 1.5 mm recessed ledge so it sits flush. Four 4 mm pockets for M3 heat-set inserts in the corner pillars accept the lid screws, and 1 mm fillets on the outside edges make it feel finished.
A printed box only helps when the posts line up with your board's holes, and that is precisely what you tell SpeakCAD. Provide the PCB size, hole positions and connectors that need openings, preview the enclosure for free, and adjust cavity height or add a cable gland hole with a follow-up.
