Flexible Filament Extruder Upgrade Threaded for Boden Tube Connectiion

This is a threaded version of Flexible Filament Extruder Upgrade. I had trouble connecting the Boden tube to the original version. It would not "self thread" and would disconnect from the part when printing began. So I imported the original model into Tinkercad and added a thread to the hole that the Boden tube connector screws into.

Worked great and the Boden tube stays in place.
