This tray is for holding Pantone Swwatchbooks conveniently and ready for use with the full title visible from the outside. It can hold a large and a small swatchbook arranged on either side with gaps for the spindle cores.

This is spiritually a remix of PANTONE BOX by ovocom https://www.thingiverse.com/thing:3324783 on Thingiverse. I started with their .STL and then rebuilt one in parametric CAD to accomodate both books, I eventually started over. This is my first attempt at creating a 3D printable model in Plasticity.
