So for future reference if anyone has a problem with the muzzles of these being too thin and Maim unsupportive telling you your printer is just not calibrated, you can cut the muzzle at 45° right after the eyebrows and make 3 to 5 copies of it that stand in the same place but each of them 1%, 2%, 3% etc smaller in that order. This will create a muzzle that is as thick as the rest of the base. No need to go into any CAD software to solidify or anything. Just adding a couple of smaller muzzles inside the main one.
