Guitar Mount MultiBoard MultiConnect Hanger

This is a remix of Make Anything's Guitar Wall Mount Hanger with Flexible Top to add support for MultiBoard via MultiConnect. This is available in 45mm, 50mm, 56mm, and 60mm versions depending on the neck width of your guitar.  For printing use 100% infill for the arm and use TPU for the padding. Use the default orientation.  The 45mm version of the arm will require some method to prevent warping such as brims, glue on the build plate, or a tacky build plate such as the BIQU CryoGrip or
