Custom Boxes (Gerust)

This is a remix, in comparison to the original I:
Added a baseplate option for the grid. Thickness of the base is in 10ths of mm due to thingiverse customizer limitations.
Translated the options to english.
Cut out some extraneous code.

I picked 25 mm square units, at 40mm deep as my standard, but that is customizable.

This is my first OpenScad model, and has two issues, the customizable version will only download you a paired box and grid. If you don't want this (which you don't), the default 3D builder app in windows can easily split the stl.

Second issue is that the Customizer sees a super thin barrier on the preview, this does not show up on created models.
