Designed this as i use a lot of small sample bits of filament, usually 10 and 20 meter samples... i found most spools on thingiverse were too big or took too long to print... so... here we have a quick and easy to print model :)

just print the hub and 3 of the arms... bolt in and good to go.

requires 3 m3 bolts but thats it :)

has a hole on each arm to slot the filament into, tight enough that it will hold it but can still remove if needed, also has a clip on each arm to clip the other end to when not in use to help it from tangling :)
