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 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.

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

Works very well. Easy to install and super durable. Should be the gold standard for 3d printers to have pre-installed.

First impressions of this item is that it is very solid and has a very polished finish. Installation was was very simple on ender 3v2. Loosen the old belt, remove old tensioner, bolt on new tensioner with included T nuts, attach belt and tighten. I was able to reuse my existing belt. So far I am happy with the quality of this item.

After fussing with the original bracket on my cr-10s for about an hour, I decided to get this and had it installed and adjusted within 15 minutes. Worked!

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