Ender 3 Flexible filament extruder M10

thingiverse

***V5 has threads and should be printed vertically. V4 can be printed horizontally and using a lighter to soften the material before cutting threads with your fitting is recommended. V6 is just a exercise for me to learn fusion 360. Its 1mm higher to make the plate stiffer and raise it into new teeth on your extruder. Trim PTFE exactly to the print because its made to fully support the filament. Print it vertical for threads that came out great. *** another junky looking but functional remix by me. When I used Klipper the frantic extruder movements made me realize the bowden tube moves in and out slightly with a M6 coupler. this M10 should fix that. while I was at it I made the hole for the PTFE tube smaller to fit my 4mm tube better and stiffened up the frame. the M10 is used to jam the PTFE against the extruder frame just like in the hot end. feed it through and seat the tube with the fitting loose. Then tighten it down to smoosh the tube into the extruder . It seems to be working very well. its near motionless now where it was plunging in and out 2 mm before. You still need a little PTFE snippet for the front filament guide. These work great for flexible filament. Chep covers the original one here https://www.youtube.com/watch?v=az7pysnV_MY
