with all due respect, the washers on either side are going to wear out pretty quickly and allow movement, this will translate to noise in the print. Any reason why you did not just buy some decent M5 idler pulleys, bearings & axle bolts and replace the whole assembly as they are only about $3 each a set??

Also worth using idler pulleys with teeth to add additional smoothness to the pulley setup

I have high-quality bearings and poly wheels for the trucks from 3dvice. As long as the belts are aligned there shouldn't be a great deal of horizontal play. I've printed well over 100 hours so far and I'm loving the setup; to the point, I'm experimenting with the same treatment to the trucks once all the parts arrive. Hey, all just theory and speculation until you try. I'm sharing my experiences with an alternative to ball-based bearings.
