Since I bought my Printrbot broken, used and missing some parts, a spool holder was needed.

I designed this with the same base as Spool Holder for Printrbot Play by dboitnot but made it thicker and changed the structure to support a 1 1/8 inch diameter wooden dowel with the same end caps that I designed for my Prusa i3 Spool Holder. (I still had some remaining wood dowel from that project). Works great.

Should be an easy print.
