Generic Bowden Extruder Upgrade for TPU/TPE

thingiverse

This is an upgrade for the generic bowden extruders found on AliExpress and Banggood. This setup offers a tightly constrained filament path that lets you print flexible materials such as TPU and TPE. To print flexibles with a bowden setup, I recommend lowering your print speed to a constant 30mm/s or less (infill, support, and perimeters), and disabling retraction entirely. This is my first post and I couldn't figure out how to upload the photos without compressing them so any advice would be appreciated.
