Creality Ender3 v2 screen holder

update 16.01: done. also, due to the fact that constant taking it off and on again to work on various mods for the printer, the previous version developed a slight wobble, I've decreased the slots radius by 0.1, and also increased height by 0.2. also, the slots are now 4mm longer. please check your printer tolerances before printing and print outside walls 1st

update 14.01: apparently a testing version got uploaded by mistake, do not dwonload, brb with the proper one, thank you @joelostberg for letting me know

original: there is another screen holder on thingiverse for steeper angle, but wanted to get rid of the "fences" on the face, so no support would be necessary
the 2 slots are for 30-60 and 60-90degrees (the shorter one) positioning
I've also replaced the screws with "normal" m4x10 hex-screws and m4 t-nut, as I find the included t-nuts super annoying
the stl is slightly different from the pictures, after printing I realized I want tho cut the corner near the longer slot
