Model/Gunpla Assembly Workstation

###Overview
I saw some model/gunpla workstation boxes online designed to help keep your work area clean by collecting the gate clippings. However, I wasn't thrilled with the price tags and opted to design my own printable compact version. Aside from the gate clipping collection drawer, there is a place to insert a small cutting mat, two side pen knife/paint pen holders, and a notch in the back to hold assembly instructions with a backing plate. The drawer slide is slightly more snug than what I planned, although I like the way the drawer locks closed and just requires a little glue for the drawer pull insert to compensate.

I'm pretty happy with the first revision, although there's some improvements I may tackle in the future:

* Removable side holder for nippers that fits in the drawer
* Sprue holder that slides into the back for storage.

###Notes
* The overall workstation box size is 220mm x 220mm x 40mm, so this needs to be printed on hardware with 250mm square or larger print a
