Changes since v6.1.0:

• Updated OKH manifest with new version and an image
  
• Split up several functions, and added more parameters to support the flat top microscope and the travel case.
  
• Fixed the hole spacing in the motor_driver_case.stl so the Sangaboard v3 now fits properly
  
• Fixed a bug where the actuator_assembly_tools didn't sit flat on the print bed
  
• Various improvements to the build instructions, particularly around printing and where to find STL files
  
• Improvements to the documentation around motor boards
