Y-Belt tensioner for Prusa i3 Bear Full Upgrade MK3.
2019-10-20
I noticed that the tensioner side-part bent a bit over time.
So I added a stronger version of it.

Replaced the stronger version of the side-part with an even stronger one with 5mm thickness.

Just noticed that the mk3 bear upgrade github repo provides a proper tensioner since Aug 18, 2019:
