I guess I'll find out as I just launched the ender-3 to do just the rim of a 240 tooth GT2_2 pulley. 8mm tall plus flanges, and about a 4mm band to fit a 145mm wheel. And I don't even have a test fit belt for profile 12 in the openscad sprocket generator. A 45 megabyte gcode file for the enders simple mind. > Cheers, Gene Heskett
