I designed this MPCNC enclosure from scratch in Fusion360, and then made a few videos about the upgrades (below).   The key features are easy panel removal for machine access and cleaning, and the magnetic half-doors allowing you to fold down the top half only, so you can access while running without completely compromising containment.  And since everything is 2020 or 2040 aluminum, it's easy to mount the electronics and an E-stop to the side of the machine. 

This primarily a design reference, to determine sizes of extrusions, wood, panels, T-tracks, etc.  There are a few printable parts:  the latches keeping the doors closed, the door handles, and the TPU hinges (only on the bottom, but would be easy to modify to use between the half-doors, as well).    I also used this to generate g-code to CNC-cut the ¾" MDF baseboard with mounting holes and T-track slots in all the right places.  However, the holes could be done by hand, and the slots aren't really necessary for T-tracks.  

I made an effort to parameterize the whole design, but I don't think it works.  It's a very elaborate Fusion design, and things like T-track count & spacing, and 2020/2040 extrusion body-split operations, didn't parameterize properly.   With the default dimensions, you get about a 17"x13" work area.  With some tinkering you might be able to tweak the sizes and get new extrusion and panels dimensions.  Good luck with that.
