Adapters for Nox Hummer Fusion S homemade cover

I have a Nox Hummer Fusion S case on my PC, and the tempered glass of the left side broke.
While figuring out if I order a new glass, put a metacrilate or other material or changing the chassis for a new one, I've covered it with a cardboard piece, and designed this pieces to fix it to the chassis using the same points of the original cover.

I am sharing this design just in case is useful to somebody else.

There are 3 files:

1 for the front pieces, which you have to print 2

1 for the back upper 

1 for the back lower

Once done printed, i've attached to the cardboard with double sided tape, by putting the piece onto the chassis, and then pressing the cardboard against it.
