Creality K2 Plus back cover

For those who said here that the back cover drops in the middle of a print here is the solution for the Creality K2 Plus.
Use the standard screws that comes with the machine (M3x5) but it should be better to use M3x8 and it's quite hard to find the same type of screws. I will appreciate somebody in the comments to share a link to buy them.
ABS/ASA required.
You can remix it.
UPDATE V2.0

After I printed in ABS, it cracked in the hole zone.

Here's the V2.0
