I did some more cutting and filing on the 300 Dome today. I am leaving all the inner dome cuts except the holoprojecters and dome bumps smaller than normal. That way when the two domes are bonded I can file them to where I want them to be. The reason I am not doing this to the holos and dome bumps is because the outer dome will cover them anyway when put together.
I put some blue masking tape around the bottom part of the dome so the two halves do not scratch on one another when taken on and off.
The bolt helps center the dome
