• AMT10 Encoder Mount (3D printed)

  • Material: MJF Nylon
  • File: encoder_mount_v3.stl
  • Note: The mounting holes for AMT103 where too large for the M3 Philip Machine Screws. A small amount of glue was used to shrink the holes. Version 4 should resize the holes to be 5-10% smaller (2.7mm) than the screw diameter(3mm). Also, the length from the mount surface to the motor shaft should be 56.5mm not 55mm.
