Hello all, in anticipation of the Airy Arm being fully developed I was wondering what kind of 3d printer I would need to make this device. My 4 year old son, Leo had a stroke in utero and has limited use of his right side, I think this could help him. I have found that no matter how effective a device is, if its not comfortable a child will refuse to wear it. Some felt lining underneath the printed framing would make it more comfortable. Also, some way of protecting the cables from snagging on things is needed, maybe a fabric shroud or narrow gauge cable housing like on a bicycle.
