Tested a print of a muzzle device after calibrating some PLA Pro. The print came out looking great. However, the 1/2x28 threads in the ID are very loose, so much that with minimal force, you can pull straight past them.
So, I’ve seen a few different ways to fix this, but I wanted to see what the community agrees to as the “best” practice to adhere to.
Do I adjust for shrinkage, add in additional tolerance in the modeled threads, or do something else entirely?

With something as stress-prone and tolerance sensitive as 2A components I think it’s definitely worth doing. Especially if you modify your printer or use a variety of filaments. Shit, my K1C came basically unusable from the factory. Every upgrade you do requires verification.
I’d rather fail a test print than a 24 hour print job.
