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 a Ender 3 Pro and the bed carriage crashes into this tensioner. <--READ UPDATE! UPDATE 9/28/21 : If you use Bigtreetechs firmware for the SKR Mini/TFT35 they change the default bed size to 235x235 instead of the default 220x220 and this will cause the pom wheels on the Y axis to hit this tensioner. To fix this change it back to 220x220!

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.

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

Not really sure if I can find a better one. The only problem is that they get loose over LONG periods of time (like I have to tighten once a month of continuous use). Otherwise, its helped my prints dramatically. Just wish I could lock it in once I got the tightness correct.

Right Bracket, wrong bolt and wrong bearings to hold the belt. Both dont even fit in the bracket! Look somewhere else

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!

This is the second one that I have purchased. Work great and you can adjust on the fly. When installing you can take the item apart and install it without messing with the belts. Happy!!! Thanks

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.

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

Easy item, lower tension to work smoothly
