Another spool holder

These are my spin on the spool rollers. I widened them by a little, lightened for quicker printing and lowered them down for more head clearance. I also added a spot in the middle so you can mount them with a wood screw. And I made them to pin together, rather than split in half. A dab of super glue on the big end is enough to keep the skateboard bearing in place.
The bearings (search 608 bearing) were purchased on Ebay for less than $1 each. The pin does not fit the bearing snug, but I doubt that will be an issue unless you are turning some serious RPM's.
