Snap-in M6 PTFE connector for hanging Multiple Mechanism Auto-Rewind Spool Holder

The Multiple Mechanism Auto-Rewind Spool Holder is a very versatile spool holder with numerous provisions to allow people to customize as required. In my case I have several of them mounted above my 3d printer feeding my MMU2. 

I wanted a simple, ideally tool-less, solution to mount some PTFE tube to the front and I came up with this, The part simply snaps in place of the round hole on the front side of the spool holder. I added a tapered hole in the center of the snap-in connector thinking that, if necessary, I would simply add a small screw to keep the edges forced apart and the connector snapped in place, but so far it has not been necessary.

It prints easily laying on its “back” (threaded hole and snap facing up) and the M6 PTFE couplers I had screw in perfectly. 

Used the Coupler Joiner as the base upon which I built the snap-in component for the Multiple Mechanism Auto-Rewind Spool Holder
