We replaced the worn-out impeller in our grinder with a 3d-printed part, and while re-installing I lost a wool felt washer that sat around the motor spindle below the grinding teeth. We suddenly had a huge problem with static; grounds flying all over the place. Eventually it occured to me that the felt washer was serving to dissipate the static charges, and after I installed a replacement, all the static problems went away.
