Filament Dry Box for 73mm spools - 6.3L

I love the original model of Dynarun but I wanted some changes. 

As I wanted to be able to fit bigger spools, I bought a 6.3L container and after the initial help of Dynarun to get a general fit, I recreated the complete model in Onshape (as a practice, still an Onshape beginner) and changed some additional stuff. Here is the list of the changes:

• Updated to the bigger container (6.3L instead of 4L to be able to handle 73mm spools.)
   
• Increased the size of the original silica holder box to be able to store more material.
   
• Added a second silica holder box on the other side to be able to store even more material to reduce the humidity even more.
   
• Added cutouts to the silica holder boxes to generate a more homogeneous environment.

This design can now handle spools with a width of up to 73mm without a problem. 

75mm spools are starting to touch the narrow part in the container, so not recommended.

I didn't have a 74mm spool to test it.

Print advice:

Nothing special, just auto rotate in your slicer, slice and print with your standard settings.
I printed everything in 0.2mm layer height.
