Smoke Box Face

Thanks to the designer for a great design.
I wanted something different for the front of mine so come up with this. I found the face at http://www.thingiverse.com/thing:293591 : but i don't own it (I hope the designer doesn't mind me using it like this).
PLEASE NOTE: I have not printed yet so can't guarantee this is 100% correct. I will post pictures once I've printed.
There are 2 different designs there.
