Replicator 2 small spool holder
thingiverse
I've recently found some filament suppliers providing a small spool with their 1 Kg filament (approx. 90 mm x 160 mm diameter with a 35/30 mm hole). I assume these come from Europe or China, anyway, they don't fit on the standard spool holder, so here is an additional one. Instructions Print both parts and press together. You should find them quite a tight fit and I don't expect you'll need the screws. I made it small enough to fit the 30mm spools as well.
