Rob Hey, just giving you haeds up that both .STP and and .STL files are showing issue with floating regions when sliced up for 3D printing.
This is fixable (if one knows what to do) but not great.
* As Bambu lab yesterday announced (or rather - gave teaser / hints) about upcoming contest and if these files will be used as a base for it (shared to community) that might turn to grand “spaghetti contest” very fast. Just something to look into.
