Anet ET4 HotEnd Fix
thingiverse
A remix of CHEP's excellent fix for PTFE tube creep : https://www.thingiverse.com/thing:4220059 Solved my extruder clicking issues, and consequent under extrusion on my Anet ET4 as well as on my Ender 3 pro. Follow CHEP's excellent instructions and all will be fine. The ET4 as a PC4-M6 connector at the hot end, hence the smaller diameter version of this spacer.
