Closed tray for Omnifixo M4.4 IM Field Box

Closed bottom tray for the Omnifixo M4.4 injection molded field box. 

The current M4.4 comes with an injection molded (IM) field box.  I first tried the closed bottom tray remix created by @PjotrStrog, but it did not fit the IM box (his remix includes a comment that he adjusted it for the 3D-printed version of the box).  The side tabs did not align with the IM box's slots, and the new side walls collided with the slots as well. 

I started over with Johann's divider, added the bottom, deleted one of the dividers to create a longer compartment, and made sure the new side walls do not collide with the box's slots.   

If you have the IM box, this should drop right in.  If you have the 3d-printed box, @PjotrStrog's remix may work better for you.

Added solid bottom and walls to the divider, so tray can be removed with contents.  Removed one divider to create a longer compartment.
