Extrudim Polydryer Drybox - studier box

I'm using the cheapest petg that I could find and that may be the reason why the original box came out a little out of shape. The sides would bulge outwards, and the axis no longer fit nicely inside. This remix aims to fix this tendency without sacrificing any usable space inside. 

This box uses only 20g more filament, and offers even more sturdiness.

Added a few extrusions to make the sides stronger and less prone to bulge during the print.
