4mm PTFE tube fitting replacement for Titan Extruder

My Original Print Broke Off Due to Weak Layer Adhesion and Couldn't Withstand Constant Retraction. I Had to Get Creative To Make It Stronger. To Start, I Printed the Part Sideways in My Slicer Program, Lowering It So That Some Surface Area Was Exposed on the Print Surface. This Ended Up Being a Great Solution Because You Don't Need a Perfect Circle Anyway. I Also Scaled the Design by 98 Percent to Ensure a Tight Fit with the Screw. The Printed Part, Along with the Tube Fitting Described Below, Can Be Used as a Replacement for the Titan Extruder Bowden Adapter. The Tube Fitting Features an Inner Diameter of 4mm and a 3/8-Inch Thread. Since I'm Using 1.75mm Filament, I Had to Experiment a Bit to Find the Right Fit. I Managed to Source the Tube Fitting on Amazon Here: https://www.amazon.com/PneumaticPlus-PC-04-03-Connect-Fitting-Straight/dp/B00BICLB2U/ref=sr_1_3?ie=UTF8&qid=1486218276&sr=8-3&keywords=4mm+tube+3%2F8+inch+thread In My Case, the Tube Fitting Came with a Chinese Copy of the E3D V6 Hot End, Which I Used to Turn It into a Bowden Version.
