This is a flared PTFE guide that goes on the end of a PTFE tube to help with insertion of filament into said tube. If I don't have my reading glasses on, this is a nice helper.
If you want to do two color pieces, add a filament change in the slicer to add just a manual filament change without using the MMU. If you use an MMU and use a purge tower to print one of these, the tower is like 5 times the amount of a single guide.
I color coded mine for my spool holders.
Print as oriented. No supports required due to progressive bridging use for the hole. ID of 4.1mm so this holds in place with a little bit of friction. If this guide is loose on your 4mm OD PTFE tube, crush the tube slightly with a pair of needle nose where the guide will go and the deformation will tighten things up. It will not hinder the tube function. Test on a scrap of PTFE if you need to test how it works. :)
