Dead of Winter (Crossroads) Organizer Stiffened

I printed ZekTheMad's awesome design for organizing Dead of Winter (Crossroads) first. It functions perfectly, excellent ideas to keep literally every piece in place even when the box is flipped over. Maybe my printer sucks or I am a bit rough with my parts, but I decided it needing beefing up a bit more.

Thanks to ZekTheMad for providing the CAD file for it. I kept the concept the same, but changed 3 of the 4 parts to be a bit stiffer so they last longer. (The tray is identical).
Per the image above, major changes include:
1) Thickened all the long walls of the corner bits 0.5 mm
2) Added more bracing against squeezing. Middle rib, corner gussets, larger shelf to hold the top, thicker corner posts.
3) Larger locking tab on corners
4) Larger holes to save material
5) Added mini walls on the LH corner to keep it upright
And a few small things.

Print times increased a bit due to stiffening:
Center Base: +17%
Corner LH: +25%
Corner RH: +17%
Center Top: +0%

I attached a SLDPRT and STP of my assembly here. Let me know if anyone would like any other files.
