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

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

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.

Perfection took 3-5minutes for me to install and I’m a not an expert it 3 bolts to remove and install its thickness is just right reliability the amount of play or stretch u get is just right u get both ends of the spectrum loose to tight makes the sheerness of the line perfectly tont took the dip out of the middle I had on mine before upgrade my printer is a cr10s 400mm clone

I had a belt starting to sag a bit so I decided to pick one of these up and its went right one easy and has made keeping the belts tight SOOO much easier.

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.

The toothed idlers wheels wobbled from the time it was opened. Everything else about this tensioner would be great if the idler was good.

It was a breeze to install and made tightening the x belt super easy. 10/10 would recommend.

This was necessary for my Ender 3 Pro; I was having stair-stepping issues after a whole year of printing and discovered that my X-axis cable kept jumping due to the slack it developed. However, after I installed this along with a fresh cable, the stair-stepping problem disappeared! I am fully aware that you can 3d print these, but metal lasts longer and it gives a more finished appearance; as if it were a part of the machine when I got it.

This works great on my CR10s and should be a 5 star product but wrong size bolts were provided. I had enough spare shorter bolts that I was able to quickly and easily install it. I bought the x-axis tensioner along with this item and that installed quickly easily, no need for additional hardware/parts.

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.
