3 servo arm designed to test the overall functionality of the SG90 servo (9g)


In theory, this will print the mountings, arm, and even a claw mounting to make the complete arm. just add servos, power, and control.

ideally, this will become a default stock print for my "Programming and Robotics" class.

"Assembled" file is just to show positioning/assembly, not intended for print.

Secondary STL files are the same parts, split into 2 prints to fit on a 15cm printing area.

Simple 9g Servo Arm - Improved
by yaniv

alas, I'm still waiting on the printer.  these are designs I've been prepping for when it arrives.
The measurements are all taken from the actual servos I have on hand, and the design is based on a prototype paper-model arm I was working on with a friend.  for small servos, they're pretty strong and the mechanics arn't complicated. 
so it should work.

when I did a slicing of this, it seemed to come out larger than the  print area.  will have to re-do the length of components to fit on a standard 5 x 5 ...
