CR-10 Flexible / TPU filament, PTFE tube push through

I printed the original about a year ago and used it a ton. After many, many many prints it finally warped near the spring holder causing some underextrusion on prints. This is a beefier version that should hopefully hold up much longer.

This is the straight- through model so you can push the PTFE all the way through and cut at an V for flexible filaments. You may need to ream out the ptfe hole a little.

Printed at .28, supports touching build plate and under the spring holder nub.
