Adventurer 3 Filament Holder

thingiverse

This is a basic, very sturdy filament spool holder. It holds normal 1kg spools. Print this upright with supports. I printed this with 50% infill but you could probably decrease this without any issues. This holder fits around the original spool holder and is a tight fit; if you're having issues try twisting it as you put it on. If you're still having issues make sure you've completely removed all supports on the inside of the holder.
