I made a rack for assistive listening devices for our church. The system has five earpieces with cords, five receivers, the minister's transmitter, its microphone, and a charging brick and cables.
I made the slots for the receivers with my 14mm cutter in the XL, overlapping the cuts for wider slots, 50 mm deep. The larger transmitter needed about a 15mm tall slot, so I had to raise the fence 1mm and repeat the cuts.
I also used 8x50 dominoes for winding the cords. The combination of the L-shaped hooks and the dominoes works well for keeping the earpiece cord loops in place, with enough give in the loops to make them easy to slip off when needed. I glued the dominoes in tight slots and filed and sanded off the reeded edges.
