Very cool! Unfortunately the sliding spoolholder doesn't fit thinner spools. For example the DAS Filament spools that I have are narrower and will not fit. This could be fixed by having the part that joins the two wheel supports straight instead of in a "C" shape.
I could not find the STEP file for this to modify it myself, but I think it should not be a big deal to change for the original designer anyway, and would make it compatible with more spool sizes.
