The problem is the Y-belt holder?

Hello everyone, I have a Prusa MK4 since December, and for the past week, the Y-axis belt has been coming loose. I assembled everything correctly and never had any issues, but suddenly the belt loosened. I noticed that the Y-belt holder component is no longer available for purchase on the website. I think there might be a replacement for the part soon. How have you solved the problem?

Same issue, mk3.9 build with Prusa PETG and the Y belt holder has lost functionality.  Pathetic.  The old design was superior but won't pass calibration with the new software.

I struggled with that problem a lot - I could print once or twice and then the belt would pop out of the belt holder no matter what I did. I tried several of the y-belt mods on Printables.com and these two together completely solved the problem and tensioning the belt is both reliable and much easier than the original parts form Prusa. Try this - you will like it!
