Okay, thought you guys would pipe-in with your ideas & suggestions......not an interest thread! 
hahahaha!
Well, atleast not yet 
Righto, let me share my thoughts:
If you noticed from the first 3 pics above, the original Nemrod holster has 3 components we dont need - namely the spear pocket (located from the top of the holster running down the entire lenght), the knife sheath and the "Nemrod" logo (I think).
The best & easiest way to eliminate this at once is if we mold the inside of the holster rather than the outside. This also makes the inside smooth so your blaster could glide smoothly & hopefully w/o scratches on your blaster paint works
The Nemrod is made out of a very rigid rubber like component which borders almost like hard plastic.....however, the straps used are pliable rubber which ofcourse we cant replicate in fiberglass. Any thoughts?
Lastly, I pressume the holster is looped around the ammo belt, correct? If so, do you want us to replicate a loop made out of FG or would you rather have this looped strap made out of rubber or maybe even leather? I dont have the knowledge on how to adhere rubber/leather to FG....so we'll take care of the FG and you guys could choose & make your own belt loop? Unless ofcourse if you want this loop replicated in FG as well.
Ideas, suggestions, recommendations......anything?
