Summary

The STLs are pointless (as this is for dimension reference) but seems the site mandates file of certain formats

Why I did this:

I was doing a project using MG90, and referenced the dimension by searching google Image, however, when the print is out, the form-factor is just a bit smaller. The manual/documents of MG90 seems not to have detailed dimension. There's a model Here, but it's in polygon ,so not convenient for projecting onto sketches as you'll have to reform the center of circle after projection. So I have uploaded step also for other design software.

• This dimension is measured using MG90S variant, so might not be suitable for dimension reference for other variant.
• As it's measured using caliper, the dimension might not be exact
  • Will be updated when error is found
  • If you find something that doesn't fit, please don't hesitate to comment, and I'll make adjustments
• The holes on servo arms is too small, so the measurement using (L1+L2) / 2 method, might have significant inaccuracy.
• The servo arm is not to be printed, but also as a dimension reference
  • The contour will be relatively more accurate
  • But the servo shaft teeth isn't accurate at all as I don't have a way to measure it.
  • If you know a way to accurately measure, please also instruct me how to do so.
• Also had servo arm built because the MG90 servo arm (stock) seems to be different from the SG90 ones ( a little bigger seems )
