Spool Filament Guide for the XL

I had a problem with TPU filament getting loose around the spool and getting wrapped around the spool holder on the XL.  I use a reduced friction system for TPU and the filament getting wrapped was a major problem.  

I created this clip on filament guide and that seems to have fixed the problem.  Now, as the filament loosens up and gets guiding back onto the spool so no more wrap ups.

It fits Prusament and Matterhackers MH build spools as is.  It may fit others or can be scaled appropriately.
