Just a small revision to the excellent filament sensor model by 53Aries and updated by Spunguh. I used a metal collet insert from E3D to finally fix the issue of the ECAS teeth cutting the tube. Collet rotates freely with the PTFE so no more tube failures - hopefully!
The collet insert I used from KB3D:
*NOTE: MAKE SURE YOU POST-PROCESS THE MODEL BY USING A RAT-TAIL NEEDLE FILE AS DESCRIBED IN SPUNGUH'S MODEL POSTING BEFORE YOU INSTALL THE BRASS INSERT!!!
Pictures annotated and pretty self-explanatory. Have had no issues with tube getting cut-off with this version. I used tight tolerances to ensure a good press-fit. STEP is provided if you need to loosen the tolerance a bit (but if your printer is well calibrated should not be an issue). Not sure about filled filaments as used non-filled PC-blend for the prototype.
Happy Printing!
