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.

The toothed idlers wheels wobbled from the time it was opened. Everything else about this tensioner would be great if the idler was good.

A great choice for anyone who wants to replace the original Belt Stretch Straighten Tensioner on the Ender 3D printer.

Its built nice, but it does NOT work on the ender 3 X belt. The pulley is too small and the belt will run against the 2020 extrusion. Now I have to order a bigger pulley to make it work. What a waste.

After fussing with the original bracket on my cr-10s for about an hour, I decided to get this and had it installed and adjusted within 15 minutes. Worked!

Excellent product, will purchase again soon!

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

Easy item, lower tension to work smoothly

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.

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
