Hi Smithy,
It is OK that the walls of the box are thin.
I checked the design in Blender and even the thickness of the bottom should be only 0,5mm. Yet when I printed it, I had a bottom of mora than 2,5 mm before I switched of the printer. Also the printing time is 2 hours and 56 minutes.....
So, how did you check the slicing?
I still have the impression I screwed up a setting, but I still don't know which one.
Btw, didn't know about the x-ray option, very handy, will correct the coffespoon 🙂
