Spool Holder or hub

This is a radioactive symbol shaped spool holder.
It uses a standard 608ZZ bearing.
I used Cura to print the file with a .5mm nozzle and .3mm layer height.
If anyone needs adjustments to the file just let me know what you need.
I made an upgrade to this part so it would also fit a 1.25ID spool here http://www.thingiverse.com/thing:247437
