I designed a new lightbox for taking pictures of my prints, and needed a light switch.the original mount's L design didn't work. Plus, I had issues with the layers delaminating because I didn't have enough space on the original design between the edges. This new version was designed from the ground up! It's a little bigger, and stronger than the original. The design incorporates countersunk holes for #6 (or 3mm) woodscrews.
