This is a holder I designed to hold silpats, but it would probably work for any small, rollable mats. The design holds 3 and they can be stacked one on top of the other.
The scad files can be modified to add more rows, make columns higher, or whatever. You'll need all 3, and the main.scad is the one that renders the whole holder.
