Creality Hi CFS Buffer Mount with PTFE Guide

I created this to allow for a completely tool & tape free mounting solution for the CFS buffer for the Creality Hi. It also includes a passthrough guide for the PTFE tube. This guide keeps the tubing straight to limit the scraping on the side of the PTFE lock ring at the end of the buffer when the tubing moves up and down. No fittings are required for the guide, and your current tubing length should still work.

To attach the mount to the printer, simply clip it to the top of the printer frame, with the mount snug against the side of the frame. The CFS buffer clips into the bottom section, with the printer side of the buffer (single PTFE tube) at the top. Route the PTFE tube from the printhead through the guide and into the buffer.
