Thank you very much for sharing! I tried to make an IIM curve brush with the cube myself as I need it for a school project but I couldn't make it weld together like yours. When I have weld and stretch on, in the brush modifiers menu, then it welds more vertices together than it should and when I turn that off nothing is welding of course haha did you run into an issue like that while making these? I'd really like to figure out what I'm doing wrong ^^"
