Spool Bearing

I made this for different style spools of plastic to rotate on. Fits Solidoodle, Hatchbox and HI-VISION HI-YIELDS spools. I use a 1" wooden rod from Michael's for the support. I would recommend something to hold the bearings in place. I used duct tape in the pictures to hold until I can get a rubber band to wrap around it to keep them in place. Works so far.
