I wanted to be able to have my filament under the table rather than on the power supply.
I used filament rollers from RzR https://www.thingiverse.com/make:370670.
I then bolted the pipe holder onto the top of power supply.
I then inserted a Bic Pen casing into the holder after heating and bending into an arc.
I was able to guide the filament into extractor without having the machine work on pulling the filament at all. No drag, and clean desk.
