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

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

So much easier to get the belts tight, easy to install, works well.

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

Installed and worked fine. Normally would get 4 or 5 stars from me. But after a couple months my printer got really loud during printing. When I held the tensioner it stopped. Turned out the bearings are crud. Took it apart and cleaned it. Tiny little bearing turned 20 qtips rusty orange. Its already sounding bad again so Ill be buying some bearings and replacing them. Highly recommend disassembling, decreasing, and relubricating the bearings with something more resistant to rust.

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

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!

Crashed into the bed while its running through the ABL process ONLY when its running through the center row. All others seem to not have an issue.

Works great!!!! I had one I printed and it worked but this is so much more fitting for the printer style....strong and slim!!! I love this x axis belt tightener!!! Went on easier than the printed one and is super solid Perfect upgrade for an ender 3

For the Ender-5 Plus, youre going to need three of these. One for the X-axis, and two for the dual-belted Y-axis. Installation is fairly straight forward and obvious. I have noticed a significant improvement in print quality since I am now able to better fine tune the tension. Recommended.

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!
