I heavily modified several models to create this all in one Mobula 8 case.  You will need to order 2mmx50mm rods from Amazon to use for the hinges and lock.  I also printed some of the inner case parts in TPU to give it a little flex because the fit is pretty tight. The small prop box lid is printed 1% smaller than the box.  The lid DID NOT FIT when I printed them at the same size.
