Herman Miller Aeron Chair Arm Support

thingiverse

I made this for my Aeron Chair because my arm rests would sag throughout the day or overnight. This helps by just keeping them at a fixed height, the design fits security and the tabs make it easy to remove. For reference on sizing, I'm 6 ft tall and am currently using the 65mm support. If you have a set of calipers set the arm to the height you prefer and measure the distance between the bottom of the channels and the bottom of the arm support.
