Flex upgrade

Cut the tube at a 90-degree angle, not flush with the V. This will allow you to push it into the gear more easily. Leaving about 1/16th of an inch exposed at the other end will give you the best results. I wanted to try this method out and see how it would work. Even if you're not using flexible filament, it makes loading PLA and ABS easier. I used a 3mm Teflon tube that fits snugly between the gear and bearing. Next, I'll drill out the heat break and extend the tube all the way to the hotend's tips. The new V5 is a perfect fit, and I moved the idler V6 over by about 1mm for better alignment. I also made some adjustments to the screw head on V7 idler for a better fit.
