It's only cracking at the muzzle where there's only 3 walls, interior, exterior and middle. It's really weird and I've never seen other bases be so thin at that part that's why I was asking.
I only get cracks when my printer is having issues, or my slicer profile is bad. Every design has been test-printed successfully (that's how I take photos) and I have used several of these (including the dire wolf) for finished heads
