-There is an outline on the bottom of the fuse showing where the gun scoop fits up.

-I form these out of .03 plastic which is .01 thicker than what i use for most of the other formed parts and the flange seemed a little thick , so just a little sanding of the flange after gluing it on and use 220 grit and then 320 blends it in better. I left an 1/8" flange around the whole piece to make it easy to mount.

-Another view

-Not sure if it will help with any kind of pressure build up but i thought i would drill a small hole in the end.
