Quick-and-dirty modification of the single-spool holder to mount filament spools a lot lower vertically. 

I printed this in PETG with an 0.25mm layer height and an 0.6mm nozzle, with 4 walls and 40% infill. You can probably get away with the default 15% infill, however, as long as the walls are sufficiently thick- they bear all the load in the default print orientation. 

Edit 10 Jan 24- modified top of hook to be thinner, as the original design was limited to ~203mm Z height before it collided with the holder. Original model is still here and has been renamed to fat hook in case anyone still wants it for strength reasons.
