UniTak3D Ender 3 V2 Y-axis Belt Tensioner Upgrade for Creality Ender 3 V2 Ender 3 Pro CR10 Mega Zero 2.0 Flashforge-Aquila AURORA-A5X 3D Printer 2040 Profile

I have 3 Standard Ender3s and this is a much needed upgrade. The price is low enough I am not sure why anyone wouldnt pick this up. It does not come with wrenches but the kit you got with your printer has everything you need. Once I found the sizes I need I uninstalled previous tension-er and had this upgrade installed in a little under 3 minutes for each of the 3 printers. All metal design gives a good quality feel. The knob lets me decide how tight I need to belt to be.

Supper easy to install makes adding tension to the x axis simple I like the fact the the bearing is groved for the belt. Should help prevent layer shifts

Works very well. Easy to install and super durable. Should be the gold standard for 3d printers to have pre-installed.

Simple to install and works great to keep the right amount of tension on my Ender 3.

Great tensioner, well built. As someone mentioned, if your bed size is set to 235mm, the Y carriage will hit the tensioner, not a problem for me since I upgraded to linear rails.

I purchased this tensioner for my Ender 3 V2 after getting a little carried away tightening the Y-axis belt and breaking the stock tensioner. This was a cheaper option than purchasing a OEM part and a much better alternative. The tensioner is all metal and I have zero fear of overtightening and breaking it. I am very happy with the purchase and would recommend it to anyone wanting to upgrade.

Much easier to tension the belt but the hole through the sheave is not bored true making the sheave wobble as it turns. Looks great but this little issue is disappointing.

Replaced a printed (PLA) tensioner on my CR-10 mini that came apart after a year or two of wear and tear. While I like printing mods in general, this is just more solid, easy to adjust and fits the rail and belt perfectly. The old printed mod was a little off and had some wiggle that led to some annoying belt rubbing from time to time.

This a solid unit already assembled ready to go! this took less than 10 minutes to install. Would have been faster but I took my time to get the correct tension with the knob. So easy ( Just 2 included hex screws NOT phillips yayy and 2 tension nuts) I am going right now to purchase 2 more for my other two Ender3 Pros. Thanks UniTak3D for a Great product and super fast Amazon shipping!

Was impressed with the quality and strength of the construction. I was happy to find out that I didnt even have to change the length of my belts. They are far superior to the acrylic parts that came with my printer
