PTFE holder used for the injection molded Spool holder - R4 with the hole relocated and rotated.

This model avoids an additional bend in the PTFE tube when a spool is placed higher than the filament buffer. It is a remix of the MMU3 printable parts \ Spool holder \ PTFE holder -> injection molded R4 version.

Remarks

The new location of the hole increases the length of the part. This causes an increase in flexibility which is good when:

• filament is pulled into the tube and friction causes strain on the PTFE holder,
• the PTFE holder is pulled down a bit because the PTFE tube is just too short.

For these cases the model is best printed in PETG because it is more flexible than PLA.

Also, a rotating spool can no longer scrape against the wall when misplaced.
