A friend's daughter has a little toy sewing machine. She only has 2 spools for thread for it. So I borrowed one and measured it for a printable version so I can give her more thread color options.I was a bit surprised that there wasn't a thread spool here, but than I realized that thread came on spools so who would want to print one?This is parametric, so you can enter the spool size, the top and bottom lip size, and the center hole size. It will make the bevels for the lips at 45 degrees so the spool can be printed without support. The .stl file is for the toy sewing machine thread spool. It is roughly 7/8 inches tall and across.
