Quick change spool setup for 8mm threaded rod

This is just a simple quick change spool system. It uses a standard 8mm threaded rod and M8 nuts like the ones that come in the A8 kit. The two bushings (52mm & 32mm) fit most all standard spools between the two of them. The plates trap your M8 nuts when tightened so that the spool is held securely in place but can spin very freely eliminating strain on your feeder for pulling on the spool. It also solves the clearance problem you have just using the bare threaded rod with most spool holders.
