3/4 way through a 9 hour print, there was some pretty bad lifting in one corner of the otherwise perfect print. In my wisdom, whilst the print was printing on the "good side" of the print, I decided to get a flat spatula and push down on the "lifting side" to try and flatten it a little. I timed it badly and the printer crashed straight into my spatula and wrecked the whole print bhaahaha... lesson learnt.
