Sandpaper Organizer with Engraving and Dremel Shank Storage

This is a simple sandpaper organizer designed to hold 1/4 sections of 8.5x11" sandpaper sheets (so, cut down the middle both ways). Each section has a vertical storage section as well for those that use thin strips as frequently as I do.

The front panel has three 2.7mm holes for engraving pen tool shanks, and three 3.2mm holes for standard Dremel bit shanks.
