PTFE Tube and Filament Guide for Spool Holder

I wanted a better set of spool holders for the MMU3 and really liked the original design but need a place to slip in and hold a PTFE tube.  

The 3MF file contains the basic shapes plus a negative volume that allows for it to slip over the right frame of the spool holder.   The model will appear as a solid object but will slice and print with the proper hole.

PETG would be the preferred material at 0.20mm with default infill settings (15%).  No supports or brims should be required.
