Over the Top Mendel Max 2 Spoolholder for 8mm Rod

This is a derivative of http://www.thingiverse.com/thing:77301. I really liked the design of the spool holder but it was designed for a 10mm tube and I wanted to be able to use standard skate bearings on my filament rolls. I redesigned the holder to accept a 8mm or 5/16th solid rod. I have printed it and it works perfectly!
Mentioned in more detail here:
I just printed mine out of PLA. This is one of the first prints that I did so please excuse the poor quality print but it functions perfectly!
