About this 3D model

The PTFE Tube for the carry handle model would slide whenever I loaded or unloaded the filament, so I designed a simple and quick print that helps retain the PTFE Tube for the external spool. It is a tight fit, so following the installation instructions below is recommended. Snapping the retainer onto the PTFE tube may damage or deform the retainer. Installation: With the tube removed from the slot in the handle, slide the retainer on one side of the PTFE Tube Insert the PTFE Tube into the slot Slide the other end of the retainer onto the PTFE Tube
