Motor frame mod for mini-afterburner. (link to the original file: https://github.com/VoronDesign/Voron-0/blob/Voron0.1/STLs/Toolheads/Mini_Afterburner/Motor_Frame_x1.stl)

This is my attempt to solve the wood grain / issue-6 print quality problem, and also make it less prone to some other issues.

Please refer to my Github for more details:
