Hi, using Cura 4.7.1 trying to print a hollow tube. The left SS shows the tube in Prepare mode and the right the same tube in Preview mode. I've rebooted Cura several times but the same keeps happening. Created original in Tinkercad. Why is there an invisible gap here? I also have another gap on the other end of the tube similar to this. ty RollerV5.stl

I'm very new to this and using Cura to adjust my prints on an Ender 5 Plus. Not sure if your insight request for for hardware or software. Using Cura it would be nice to have an export of the entire visibility settings. Could be text but .docx or ,pdf would work. I could then add space for my notes to add or exclude based on the project. There is an export function but it creates a cura enable file type. *.curaprofile ty Phil
