Titan extruder upgrade idler arm

thingiverse

This is the proper design for the Titan extruder idler arm. The filament will always go properly inside. Also it has hole for zip tie to hold upper 4mm PTFE tube in place. The bottom PTFE 4mm tube just goes into the hole (the plastic insert part could be cut short or even completely omitted). Use the same original Titan idler arm bearings. No support needed. I printed it with 0.3mm layer. The only thing needed is to smooth the 2mm filament hole with the drill bit.
