Presenting the remix of the remix.
This is a mounting clip for an Azteeg X3 and designed to slot into the center channel of an OpenBeam extrusion.
The center hole is sized for an M3 x 8mm cap head screw. Secure with a DIN934 M3 nut inserted into the extrusion slot.
The is a modification of blah_59's design @ http://www.thingiverse.com/thing:150566, originally sourced from Steve Graber.
The design now has a slightly wider central screw hole, and slimmed down channel block based on test print results, which should make it easier to install. If you downloaded this design prior to 1/13, you do not have the latest version.
