This is another filament holding spool for loose coils of filament.

Print the parts
The arms are to be glued to the hub with PVC pipe cement. This works perfectly well with both PLA and ABS. Allow 24 hours to reach full strength with PLA.
The hooks are adjustable.
Use a short piece of 3mm filament as a pin to fix them in position.
You can melt a knob onto one end.
If you put a kink in the filament it wont drop out.
Use an M8 bolt or some threaded rod as the axel.
The base needs to be weighted down so that it doesn't get dragged towards the printer.
The base was intended to perch on top of the threaded rods of a prusa-mendel but that position interfered too much with the filament.
Sorry the files aren't named very well.
