Spool Holder Hook with PC4-M10 Filament Guide

I love the Spool Holders by Copanko and wanted to use them with the MMU2S. The Hook For Spool Holder by George is perfect for holding 5 of the spool holders in place on top of a Lack Table Enclosure. The only downside is there is no PTFE tube guide for this design so I made one. I designed this one to have a PC4-M10 fitting.  Any feedback is greatly appreciated.
