while this helps the belts, if it's still not properly centered the belt guide will now rub and cause extra un-needed resistance that can affect print quality depending acceleration and such... it's just best to not use this as a bandaid fix to the real problem.... FYI...

Yes, you still need to put your best effort into assembly. If you're having trouble with these my only recommendation is to adjust and recalibrate your machine and print new ones. I've been using these for a year and a half. They work great. Since they are friction fit they won't move on the bearing and stay centered. I've never had rubbing. I have wonderful precision prints that make people with much more expensive machines jealous.

Great idea...when I saw the belts on the stock idlers rubbing against plywood I wondered how they would fair over the long haul. Made a couple of these and now I don't have to worry about excessive wear. Thanks for sharing!

I've been using them for about two and a half months now and they still appear to be in good shape. My printer probably runs on average between 8-12 hours a day. Just make sure you take the time to print a high quality piece the first time so that you don't end up causing damage to the belts. Something I discovered after a few weeks of use; attempt to align the screws the bearings are sitting on as if you didn't have the belt guides. The belt guides help a lot, but if you neglect to properly align your belts and pulleys then belt rubbing and damage can still occur. I discovered a lot of rubbing on the x-axis idler pulley since I didn't sufficiently tighten the two bolts holding it in place and the belt pulled it out of alignment.
