The file 'Filament Gear/knob For Anycubic I3 Mega 3D Printer Model' is (stl) file type, size is 997.4KB.
It fits over the 5mm peg/stick on the filament pushing part. This is an unoriginal idea, Make Anything made this for his cr-10 but the knobs are slightly different sizes. so credits to Devin. anyhow, this is very useful for loading filament when I don't have both hands or I don't feel like hitting my head on the shelf of my desk again.
