Update 2-2-16 Reloaded the files because there were reports of the old files being corrupted. So use the v3 version to be safe. The files otherwise should be safe.
This is a mounted spool holder for the Micro M3D printer (not sure if it will fit the Pro). I took two different designs and smooched them together. One from here: http://www.thingiverse.com/thing:528407 the other was from "Mark" from the M3d forums.
Someone else also made spacers for my holder you can check it out here: http://www.thingiverse.com/thing:753630 They are not necessary and you print fine without them but they can be useful.
OK hope you enjoy it!
