ESun Spool To 13mm Shaft Adapter

*Quickie Update 11/30/16 - I added a 1.1 version of the adapter to the files in case some of you were finding that the original was a little loose in the ESun spools. The 1.1 version bumps up the diameter to a straight out 52mm, where the original is about 51.8mm. It may not sound worth troubling over, but believe it or not, 0.2mm actually does make the difference between fitting loosely and fitting snugly. YMMV, and I'm keeping both files in there just in case the 1.1 is too tight for some user
