Excellent build quality - Ender 3 v2 install a snap

I purchased these replacement tensioners for my Ender 3 v2 since the stock plastic parts had started to crack and fail. These are very well built and easy to install. Exactly what I needed. A word of caution for Ender Extender 400 v2 users, the X gantry tensioner may just barely fit and pull the belt tight, this may be due to the different length belt but it doesn't have much room for adjustment.

Pros

Significantly reduced backlash

Cons

The tensioner may not be as effective on printers with large build volumes
