This spool holder was designed for the Joel Telling spool holder contest. You will need 4 standard skateboard bearings to go in the ends of the 2 2mm tubes. To help the bearings stay in place you can put some painters tape around the outside of the bearings depending on their tolerances. The only part that requires support material is the mount and leave it in place until the spool holder is assembled. To assemble the spool holder use a rubber mallet or similar to tap the pegs into the mounts holes. Don't forget the put the 2 2mm tubes in place while using the mallet. (No glue Required)
