ptfe connector

thingiverse

This is a ptfe tube connector, it's designed to avoid the movement of the ptfe tube due to retraction. One major problem with ptfe tubbing in my hotend is the damage cause by metal blade in the connector. After a while the tube is damaged and move a bit, this can produce clogging. I have not tested the heat resistance for the moment, and wondering if I can get the same design with metal parts.
