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

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.

The description says it fits the Neptune 2. This absolutely will not fit the Elegoo Neptune 2. It does not even come close to fitting the rails. If you are buying this for the Elegoo Neptune 2 don’t, it won’t fit.

This worked quite nicely in my CR-10. Its great being able to just turn a knob instead of pull on something and tighten bolts. If you know, you know.

Tightened up the slop in the x-axis and smoothed out the issues I was having with precision with the prints.

Much easier to tension the belt but the hole through the sheave is not bored true making the sheave wobble as it turns. Looks great but this little issue is disappointing.

It worked as intended on my Ender 3 Pro

This has made getting the belt on my Ender 3 super easy and fast. For my ender 3 I did not have to re use any of the standard hardware which many people said they had to. I did not and I did not have to take the belt off to install this... I did have to take apart the entire part but it is straight forward and easy to understand.

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.

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

High quality aluminum construction, belt can be perfectly hand tensioned. Super easy install. Must have upgrade for creality machines.
