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

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.

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.

I installed this on a Longer LK1 (Alfawise U20) and is does exactly what I wanted it to. This part is well designed and manufactured with precision. Surfaces are smooth and square with no burrs and the bearing is quality. It also ships with quality fasteners/hardware.... not the cheap, mass produced stuff that usually comes with attachment pieces and easily strips or elongates. Purchase with confidence - you wont be disappointed.

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.

Excellent product, will purchase again soon!

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.

could have a bit more adjustment, needed to use my screws on the ender 5 pro. Bought 3, 1 for x, 2 for y

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.

Easy to install on my Ender3, and it makes it much easier to maintain proper y-axis belt tension by allowing me to use the screw to tighten or loosen the belt. The entire replacement process took around 5 minutes and print results are just as good as before. Yes, you can print your own parts, but this one is made with metal so you dont have to worry about subjecting the part to too much tension. Affordable and easy upgrade to the stock y-axis belt tensioner.

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.
