CTC i3 Top Mounted Spool Holder

This is simple spool holder for the CTC i3 Pro B printer. It will probably also fit some of the other i3 clones out there, such as the Geeetech.

Just remove the two screws from the top right of the frame, sit the spool holder on top and put the screws back in. Uses the original screws so no extra hardware needed.

Uses the axle part from the original spool holder that come bundled with the printer.
