I bought a used Prusa MINI+ which had been upgraded with a Slice Engineering Copperhead Hotend.
The machine was missing a hot-side PTFE collet clip.
PTFE collets without clips have a tendency to allow up/down movement of bowden tube upon retract and refeed, adding unwanted hysteresis to the filament path and decreasing print quality.
I printed this out of PLA at 100% infill on said machine - total print time ~4min.
Slid on and rotated 180* for more confident retention.
Seems to work well. Enjoy.
