Z Axis "Squeaky" noise fix

After a few months i bought my X1C I've starting hearing some “squeaky” noise when the Z-axis was moving. It happened when the bed was on the highest point or near the bottom.Started searching what could be the issue and the fix for this problem.The common one was that the Z-axis belt was rubbing against the pulley wheel.And the common fix was just add some oil on the pulley. But for me wasn't a real fix.So i've started doing some tests and can say that i found, maybe, a real fix for this problem.I've noticed that the plastic that holds the pulley was bent so the pulley assembly was not straight causing the belt to move on one side rubbing the pulley wheel causing the “squeaky” noise.What i made is a spacer to this plastic part and a washer so that the pulley assembly remains as straight as possible. Before doing the fix remember first to print the parts first or use another printer.Follow this guide: https://wiki.bambulab.com/en/x1/maintenance/replace-the-z-timing-belt
