BCG & CMMG BCG Carry Case

thingiverse

I leave my BCG out of my gun for storage as well as swap between it and CMMG bolt. I needed a place to put it to keep my bags from getting greasy. I'm just in process of printing the CMMG lid to see how it fits. Word to the wise this thing is a tight fit, so before you print the whole thing, Z cut a 5mm cross section of it and test it with your printer. If its too tight scale everything up the same (then all the threads will still work). I generally printed the top 10mm and the screw cap to see if it all worked and thread together.
