Print optimized - Second PolyDryer Desiccant Container

Remixed the https://www.printables.com/model/941851-second-desiccant-container-for-polymaker-polydryer since it was a bit rough to print. The circles were taking up a lot of time and the support for the upper overhang wasn't nice to have. 

I've removed some overhangs on the inside (so you can print it without supports) and removed the circles, replaced them with squares. The squares are 1.5mm, so smaller desiccant which is often mixed as 2mm-5mm balls shouldn’t pass through so easily.

Grab the lid from the original design, the fitment for that isn't changed. 

Changed the holes and some internal geometry
