Inline Filament Buffer - CFS AMS Helper - Beta

The main aspects of this, however, are completely unique.If you would like to support my efforts, buy me a beer. I want to keep my projects free, and your support helps me do so.This inline filament buffer was designed out of the desire to use retract before cutting on the K2 Plus with CFS.
