i bet that's the problem. i keep checking off inches as the units when i upload the model because that's what i designed it in but the units being off definitely would be causing this issue.
the motor mount is the same in both places. the size shape way's says for the set of parts is 2.532 w x 4.938 d x 2.94 h but it shouldn't be much over 1x1x2. i can't figure out how to change the export units
