I was tired of my spool constantly unraveling, and hanging it on some of the extra conduit seemed too simple of a solution to stick with permanently, and thus I designed this! It's based on the shape of the 'Flashforge finder spool holder with filament guide' by kvasbo (Linked in the 'remixed from' section). It holds onto the conduit well enough, and keeps the filament nice and taught while printing. I included the SolidWorks files to allow for easy modification for different size spools or conduit. I'm using it to hold the 1.2 kg 3DMars filament spools, and it hasn't dipped yet! The image above is of an earlier version, the newest version has a thinner filament guide arm, as visible in the .stl files.
