I’ve been trying to force these objects/barrels to print with a solid knurled end but my printer keeps seeing the objects as hollow no matter what i put the infill at 100% or not and I don’t seem to have the software to fill them. Can you look at these and tell me what it would take to force the knurled end to print solidly? Any help appreciated as well, not looking for a handout and I’m very interested in learning how I can do this on my own. Thanks again!
