Flexible Filament Extruder Upgrade for Tronxy X1

This is an upgrade for the Tronxy X1. It will allow this printer to print with flexible filament more reliably using a PTFE insert to close the gap in the extruder that normally allows TPU to get jammed. This project requires a 13mm section of PTFE tube for 1.75mm filament cut to a point along with the 3D printed part.
