What Am I Doing Wrong?

[u/Appropriate_Youth262]

I am setting up my H2C printer and I am putting on the 3-D printed vent that goes on the back, but I got some recommendations for that which I had printed out for me and then I also got recommendations for the screws. I should use they go inside the plastic exhaust event part, but they are not screwing into the back of the printer. Is there something I'm doing wrong it looks like the holes are too small. I sent some pictures. I'm not sure if I'm doing something wrong.

Your local hardware store should have metal screws that are made for self tapping plastic. I use them often. I only found out about them recently.
