Have a spool holder from RoBo 3D ?

Does your large spool keep sliding off while printing

Look no more

This is an extension for the spool holder that was shipped with my Robo 3D, the spools kept slipping off the spool holder

With the custom spool holder you can also use this Filament Guide to reduce friction of the filament at the edges of the printer and while feeding into the slot on the top

You have a 3d printer, just make a better spool holder.

I printed my own that mounts on top of the printer itself.
