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

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

Works well - easy install

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.

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.

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!

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.

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.

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

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.

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.
