How to kill the inner "wall" on this print?
I designed and printed this lamp body and the first time I printed it, it came out like I wanted, with just the ribbed body. Somehow during my various redesigns and prints, I made it so that it now always prints within an inner "wall" or "sleeve" that I don't want. I've tried repeatedly to recreate the first attempt (Shapr3D) but can't figure out what I've screwed up. I realize the shell thickness is different on the second one but I've tried over and over to adjust that and it never seems to make a difference. Any ideas?
TIA!
