PTFE Anti-Bend Adapter

When printing models with multi-colors using the AMS, I ran into an issue where the filament would get stuck on the final PTFE coupling before the printer. I believe it is because the PTFE tubes aren't straight in my current setup and the filament would hit the wall of the coupling. This adapter solves that problem by keeping the PTFE tubes in-line so the filament flows right on through. 

This adapter slips on after assembling the PTFE tubes into the coupling so you can add it to any existing setup.
