TEVO Tarantula PTFE tube mount

thingiverse

I created this when my push-in hose fitting broke on my tarantula. This piece replaces the gold-coloured piece that the push-in adaptor screws onto. I've found this design to be even better than using the push-in adaptor because now the tube doesn't move at all. Previously there would be a bit of movement of the PTFE tube during retractions, which meant that the filament wasn't being retracted properly. Print Settings Printer: Tevo Tarantula Rafts: No Supports: No Resolution: 0.2mm Infill: 50% Instructions Print the part and thread a M4 nut onto the PTFE tube about 5mm up from the top. It's easier to get the nut on if you cut the tube at an angle first. If the nut compresses the tube slightly, run a 2mm drill up the tube to clear it enough for the filament to pass through. Then push the nut into the holder on the part, which should be a snug fit but still doable by hand without too much force. Screw in the part in place of the old gold-coloured piece.
