MultiBoard/MultiGrid Bin Insert Sanding Drum Storage

Here are four different sanding drum storage options for MultiBoard MultiGrid, or they could be stand-alone containers. There is a large, medium, and small vertical drum holder; each of these three holders has a hole for the mandrels in the center of each post. Then, there is an all-in-one holder for up to three sanding drums per slot and some holes for the mandrels.
