Thanks, I'm pleased you like my solution. I do not know of any which works for the x-axis. There are some similar things on Thingiverse but they all require you to either remove the pulley or leave your pulley misaligned. I'm working on a solution which replaces the x-axis motor mounting plate for a printed one which accomodates for a damper without changing the motor-offset. When it is done and I'm satisfied I will also post it on Thingiverse.
