After numerous failures and many reprints, I finally managed to get the treehouse printed. It consists of 11 separate pieces.
There were problems galore...…...
To start, it was layer shifting which is now resolved.
Then Supports were too firmly adhered that it was hard to be removed without parts got broken easily. I had to compromise a little on the spiral stairs and the railings or treehouse will never get done.
Then Parts fitting left a lot to be desired. I used to be a model car modeller. I know about parts fitting.
That said, a pretty decent treehouse has been printed.
No pain, and gain.
