If you don't have a dremel you should be able to drill a bunch of holes and cut chunks out then clean up the keyholes with a file.

I used an exacto knife on mine.

HAHA i build modle cars all the time i dont know why i didnt think of the exacto knife...ok thanks. oh any ideas on the grate in the back?

Just screen window screen is what i used.

this is probobly stupid but on my old one I just used a drill bit and the friction just cut it. (didnt do a very good job though)

I just window screen but, I used 2 layers and made them cross in and X pattern.

I also used black screen. glue the first layer horizontally and the second layer (inside) diagonally. Just my 0.02 cents.
