Filament holder

This is the Official spool holder made my us at Endlessparts.com it will hold the low filament sensor. right now it only works with the classic size spools.

to make it work really well you need two standard skateboard bearings, but i have tested it without them and it will still work.

its has a place for some neodymium magnets to help keep it stable but they are also not necessary for it to function.

here is a link to the low filament sensor
