PTFE Tube Router

thingiverse

This is a straightforward component to assist with routing a reverse Bowden setup. My spool holder resides on a shelf directly above my non-direct drive printer, and this gadget helps route the filament through a PTFE tube down to the bottom shelf. It's designed so that you can screw in one or two hotend Bowden fittings into the larger holes, which keeps the PTFE firmly locked in place. Feel free to modify it as needed.
