So I got my Octave Enclosure for my Afinia printer (http://www.octave.com/p1173433209/Octave-3D-Printer-Enclosure/product_info.html) and it didn't have any spool mounts on it. I ended up whipping this up from a pervious modification I made to their universal mount for the Makergear M2.

Just a side note, Octave has updated all of their spool mounts to work on the enclosure or printer...but I didn't know that at the time, and I like the old style better. :P
