This is a servo mount adapter. I was modifying a R/C car. I needed to switch out the 4-wire motor controller up front for a 3-wire servo (in this case, an HS-322 HD), but the original control was screwed in vertically while the servo needed horizontal fasteners.

1. Modify file as needed for the size of your servo and for the vertical risers.
2. Print out mount.
3. Screw in servo to the horizontal section. I had to use spacers on the screws here.
4. Screw the adapter down to the vertical risers.
