I ran the printer for a while without the filament guide, and when retracting, it made the spool bounce around a little more than I was comfortable with. I built this as an alternative to the top guide provided with the printer. You can print this guide with PLA or any other filament and with no supports needed. Reuse the clips from the guide provided with the printer sliding the tubing from the top toward the build plate.
The author marked this model as their own original creation.
