Thread Spool for Norvise Fly Tying System

Replacement/spare spools to be used with the Norvise clutch bobbins for fly tying. Dimensions are tweaked slightlly fro,m the original to print cleaner but fit and operate like the originals. They are by no means a replacement for the machined spools which will last a lifetime, but its a nice option for the lesser used accent/finishing threads, traveling etc. Note that the print profile uses support for PLA on the support interface so AMS is required. You are welcome to mess around with different orientations etc. to get a clean print another way, but after about a dozen different attempts, this was by far the most sucessful
