Steve3d @TheClayKnight OK, another order was cancelled for the same revision, within 24 hours of yours, the issue was infact not a turret, nor was your order printed; It was a tiny block, hanging out in space off the stern which caused the issue. It was too small to print, but obviously shouldn't have been there. So previously this was a non-issue as it wouldn't resolve anyway, despite there being no returns for the previous 6 prints, someone this time decided this tiny free block was an important part of the model. anyway, the model is fixed and more importantly improved, thanks, i appreciate your support and patience:)
