I like how DRÁTENÍK's filament holder clips onto the spool holder instead of the printer frame, but I wanted more clearance above the extruder to the guide. This is both to allow room for my filament wiper sponge holder and my perceived concern about constraining the filament too much when the extruder is printing nearly at the top of the print volume on either side. I sized this to clear a Prusament spool. Larger diameter spools may cause issues. I clip mine to the 4th notch above the printer's frame. Here is a picture contrasting my remix to the original:
I created this remix in FreeCAD v0.19pre (it doesn't load properly in v0.18.4). I traced the spool holder clip and the filament guides and designed the support myself. I discovered in my first test print that the height of the gaps where I want to clip into are taller (by about 3mm) than the bottom one that the original clips to. Thus my remix won't fit in the original location.
I've included both the FreeCAD file (the .FCStd file) as well as a step file if anyone wants to remix this.
Finally, here is a timelapse of me printing this model on my MK3S:
