ProsperPlast NORP parametric boxes

To all users of the excellent ProsperPlast NORP organizers: We all miss some boxes of exotic sizes. There already are some excellent variations on Thingiverse ( https://www.thingiverse.com/thing:4617525 , https://www.thingiverse.com/thing:3376439 )
However I took this as an exercise in parametric modelling and created something new.
The wall thickness is 1mm like in the original.
Enjoy

BTW: As I like to store my screws along with the proper scredriver bit: I have included an optional bit holder in the box. Include it or exclude as you like.
