And progress from the past few days. Calling the back completely done!


Not too happy with the top section here, but it really shouldn't be seen all that much.
As for the magnets, I went with E6000 to adhere the magnets on the sides, then a contact cement the 'decorative cover' and will add another layer of eva foam on the bottom also with contact cement, just to be sure.

The design should be raised, but if I made it out of foam, it would be squished when a weapon is mounted, and if I 3d printed the detail, a weapon wouldn't sit flush. Probably over thinking it, though. (and no matter how I shaped that hexagonal piece, it kept leaning right...). These magnets are pretty strong, too. I actually had some trouble with the section, I tried dremeling, but magnets pulled the dremel's head and damaged it. Its why there is so much kwik seal there.
Between kwik seal applications, I began fixing up the helmet. I tried to fix the side vents as is, but eventually just cut them out and started over with foam. Also, used some kydex to cover up those weird ear holes. Along with sanding down the molding at the seam lines and filling it. Another thing I did was try to widen/deepen up groove lines that are supposed to be there, to define them more.

I know there's better stuff than kwik seal to fill these gaps, and probably take a few more applications, but its what I have on hand. But its looking a lot better than how it came.
