Tried making one arm with elastic thread, based on the model from yesteday. 2mm ish acrylic with spacers, 20 layers. The market was closed by the time i got there, so will try to go again today to see if they have any other material.
It is pretty flexible and there's not too much resistance, however i think maybe rubber bands of the same size could be better? Also I think it could be possible to limit it to three threads instead of four as well to reduce resistance even more.
