Floating Filament Guide for Octave Spool

thingiverse

This is a spool support that mounts on the same axle as your filament cartridge, but independently. It floats up and down to keep the filament in line, stopping it from getting tangled around the axle. Made for use with Octave size spools, it's been designed to ensure hassle-free changes between cartridges. Just slide it into/out of the loop-shaped arms on either side of the axle and you're good to go. With 5% or less of the filament used up, it works beautifully. But if using a new cartridge, be patient - some slipping can occur initially. To install, simply print one guide and two arms; it's a breeze to figure out once in hand.
