About this 3D model

The spool's width, diameter and spindle size can be customized but its main feature is it prints as a single part without needing any support. *Updated:* - Added a selection for a smaller spindle. - Displays estimates for how much the spool can hold by weight and length. - Performs some basic checks to make sure the spool designed can be printed. - Does a better job at limiting the diagonal walls to a maximum of 45 degrees.
