I'm sorry my friend, but the model is very bad. 15 hours were wasted. The holes at the end of the barrel are crooked. The supporting rods are too thin for the slots in the model. 10/1
sounds like it could be a few things, best thing to do sometimes instead of wasting”hrs” open it up in the slicer and cut a piece out print it, test it. but the fact that everyone else has had no issues: user/machine error, printing from ur phone, comp? what slicer, and are ur using his setting?
