PCB Holder Storage

I needed a place to store my PCBs before assembly or in between soldering parts.The holders are optimized for 1.6mm 2-layer or 4-layer PCBs (gap is 1.71mm), distance is 12mm – use every second slot to allow higher parts on a PCB.Slots are multiples of 5: so 5, 10, 15, 20, 25. Let me know if you need a different configuration.
