3D Touch (BFB) USB Port Dust Cover

thingiverse

An enclosure for the unprotected electronics on a 3D Touch printer's small USB interface PCB is provided by this snap-in piece, held mainly by friction. Though it could be modified to include real snap fittings (design file included), its current design keeps it securely in place. The original design has been revised and shortened; the tall version files are deleted but its photo remains. The cover installation involves sliding it under the lower horizontal frame bar, then maneuvering it over the USB jacks to fit into the semicircular cutouts for screw head clearance. This cover protects exposed conductors from potential shorts and prevents dust accumulation. New files are available for the revised, shorter design.
