Model is tight fit.  Recommend 102-104% scale for easy fit, if you don’t know use 104 as your bolt will always fit.  My setting was 102% for a fit without calibrating filament

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. Remember to scale both your lid and body to the same*
