Step 2 Cut the perf board

Figure out the inside dimensions of your box, and cut the perfboard to fit it using the Dremel. For my box, as listed on the order sheet, the dimensions were 3.10" by 1.96". For that box you'll also have to cut holes for the screw slots and the board mounts. I dripped some wax on my board and pushed it into the box to see where to cut.
