I was trying to locate a shape generator or codeblock? that is similar to the shape generator- "adjustable box" but for a tube or circle. Wasnt sure if it existed or where it might be located. I really like the Adjustable box - easy to select some dimensions and thicknesses and print the box and the matching lid. I would just like to create a 'round box' and make a matching lid for it. I think i have seen something similar made of cardboard that posters get stored in or mailing tubes and was hoping to duplicate that basic design. Any know if this is available ? Thanks in advance.
