This is a bracket to hold the Universal Spool Holder by jjpowelly http://www.thingiverse.com/thing:943563. It's designed for the 80MM rod size I'm using for Hatchbox filament and My NEW Folger Tech FT-5 on the top 2020 Bosch tubing. It does have a bolt hole but it's not needed. I also designed it not to need supports.
