This is a mount for Big Tree Tech's Kraken.  I needed a mount to add this to the all in one enclosure I am designing (I hate tipping my printer over to work on something).  

It has provision for M3 x 4 x 5 heat inserts.  These are centered 6.5mm under the board with 150mm spacing.  I labeled the motor side of the mount, as the mount is not symmetrical.

Version 1.1: Added through holes for the horizontal mounts, allows for longer screws if you run out of short ones.
