3D printer enclosure - plexiglass holder

i build a enclosure with 4mm MAKROLON® for my creality ender 2.
The corner holder are assambled _IN_ the case to hold the plexiglass with m4 Srews.
All holes are 4mm and have a 10.2mm embossing for neodym magnets
I decided to make 2 sides removable with the magnets.
(i bought these ones -> https://www.amazon.de/gp/product/B07BXHQ344/) and on the glass i put these metall plates -> https://www.amazon.de/gp/product/B01N4QIIQ4/)

so the cube has 3 fixed sides(inkl the top) and 2 removable sides in my case left and right side..
