Festool SYS3 237 150mm sandpaper inserts

System for storing 150mm sandpaper disc's in a SYS3 237.The bottom is the bott/tanos/sys3/festool org bottom. Printed in 4 parts with connectors.The boxes are 2x7, 3x7, 4x7 and 5x7 in size.The bottom grid needs support under the cross in the bottom. It also needs to be split into the different parts in the slicer.Depending on the box configuration there is 10-20% more space, but the big difference is that you can deside the size of box for certain sandpaper - unlike the festool foam insert.
