Hammond 1551KBK ABS Enclosure (80x40x20)

Slid my prototype board right in without any modification—the internal PCB mounting bosses are perfectly aligned. The matte black finish looks professional enough for a final product but it’s still light enough to pocket.

Finally scraped together a proper enclosure for my little sensor PCB and this thing fits it perfectly, the 80x40x20 footprint is just right. The ABS plastic feels sturdy enough to protect the board, and the miniature size keeps my project neat without taking up desk space.

I’ve been using this box to house a small sensor board, and the snug fit for a 80x40x20 PCB is spot on. The ABS plastic feels sturdy enough for desk use, and the screw holes lined up cleanly on the first try.
