AutoRewind Spool Holder for SnapMaker A350

thingiverse

Variation of the Auto Rewind Spool Holder to be used on the SnapMaker spool holder rod. Used with an A350, it will likely work with smaller versions of the SnapMaker 2 as well. This modification solves the issue of filament coming off the reel when the machine moves to home position. Default setup is for a small spool with a 32mm diameter hole (generally a good idea even if you don't have a small diameter spool), and an adapter for a 64mm wide spool with a 53mm diameter hole. The secondSpoolInnerDiameter and secondSpoolWidth are the two settings to change for different spool adapters. Once you've created the basic set of parts (spring, hub, protector, tabpin), then create as many different adapters as you need. It was suggested that including a set of STL files would be helpful since most will be needed for an A350. There are files for a 32mm diameter hub (smallest spool I have) and adapters for the three other spools sizes I have. Adapter-32-{dia}x{width}
