FilamentBox Grommet Knob modified

thingiverse

I wanted to use the Filament Box Grommet by Flip_Schaumal but I didn't like the open-air connection where the filament goes through. So, I decided to design a new knob that would improve this setup. This knob has a PTFE tube connection built in and can be easily placed on top of the existing Filament Box Grommet. The PTFE connection isn't fixed to the knob, which makes it easy to turn. When the filament goes through the tube, it creates an air-tight seal that prevents vibrations from the extruder from traveling through the filament and causing strange noises. I used 10mm connectors from Amazon to create this improved setup: https://www.amazon.com/BIQU-Straight-Pneumatic-Connector-Extruder/dp/B01IB81IHG
