Anycubic Mono X Wham Bam alignment tool

I made this to make installing/aligning the Wham Bam flex plate quick and easy. This is for the Anycubic Mono X flex plate system. I printed the tray in PLA+ and the feet with Ninjaflex Midnight, though the feet are not necessary. The screws I used were M4x10mm flat head screws, with a washer and nut underneath. 

The tray is 212mm x 138mm x 17mm and could probably be made on the MonoX if oriented vertically, but I used my Artillery Sidewinder X1 to make it. Step and Fusion 360 files provided so you can fiddle with it if you need.

*** UPDATE ***

I have removed the cutouts for the little magnets and added a cutout for the tab on the left side so the flex plate can be flipped over and still fit in the alignment tray. I swapped the stl/3mf file but not the step/f3d files. If you want them, just leave a comment!
