Cobra and adapter bracket for Malyan M150

As per the original Cobra's instructions, print with supports touching the BUILD PLATE ONLY!

This is a remix of the cobra that includes a bracket piece to allow mounting the cobra to the M150 without having to replace or tap/drill the bearing blocks.

The adapter should fit snugly around the extruder stepper motor and the lower bearing block. There is an unused mounting hole that the middle piece should fit into for added stability. I used superglue to adhere the bracket to the fan duct.
