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

Super!! This addition to my Ender 3 Pro is amazing. No more do I have to balance pulling on the wheel and keep tension on the belt while I tighten the nut. This product makes it a breeze. And it is good quality. Anodized Aluminum with easy install. Highly recommend.

Its been said a time or two that these things can be printed instead of purchased, but Id like to counter that point with a couple of my own: 1). What if you need this because of troubles youre already having with prints? Cant really print the replacement too well in that case. 2). How much is your time (and filament) worth to you? Because this simple add-on cost less than the amount of filament Ive wasted trying to figure out whats going wrong, and could have saved me 2 days of wasted printing time if Id thought to buy it sooner. Im all for printing things that you need customized just for your particular needs, like a desktop tool caddy, but for this? Just buy it already. Its made of more durable metal, is dead simple to install, and provides a feature that honestly should have been stock on this printer in the first place! Within minutes, I had this installed to my Ender 3 Pro, and belt slack was gone seconds later. Great bargain, looking forward to enhancing the y-axis later, too!

Great fit and easy install on my CR10 Max. This tensioner is a must for all Creality 3d printers.

This really helps keep the x axis belt tight. Has really improved my print quality.

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

This is very good for the price, highly recommend this product

Works well - easy install

This works great on my CR10s and should be a 5 star product but wrong size bolts were provided. I had enough spare shorter bolts that I was able to quickly and easily install it. I bought the x-axis tensioner along with this item and that installed quickly easily, no need for additional hardware/parts.

Easy item, lower tension to work smoothly

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