Removing those was the first thing I did (after resizing), since a lot of people remove the turbo buttons anyway, and the screw holes can be - and really should be - cut out easily enough by lining the printed art up against the plexi top and cutting. In fact I plan on removing the button holes from the finished version as well. This should make it so that any minor cutting errors don’t result in visible white areas, and you can use the cutouts in transparent buttons if you want.
I only left the holes there for the small versions so that you could see the overall picture.
Also, on an unrelated note, you shouldn’t quote images the way you are doing. It makes it harder for people to read the thread. Just strip the IMG tags when you quote. I’m actually going to do that for my previous posts since those images are no longer of immediate relevance.
