This is an improved design from the Solidoodle Spool Holder Mk2 by gsterley All I did was extend some extrusions to make the design stronger and fit better. The part of the arms that goes between the brackets wasn't nearly long enough. I also make a block on the top of the arms to stop the pvc pipe from slipping out.
