ENOMAKER Upgrade Ender 3 Belt Tensioner X Y Set for Creality Ender 3 3D Printer X-Axis(2020 Profile) and Y-Axis(4020 Profile) Synchronous Belt Stretch Straghten Tensioiner(Blue,2 Pack)

This was an excellent upgrade to my original Ender 3 printer. The X-axis wasn't too difficult to install. The Y-axis was a bit more difficult, primarily because I didn't want to remove my bed plate, giving me very little room to unhook the belt from the Y-carriage. It came with no instructions but thankfully it wasn't too difficult to figure out.Prior to this, it required a bit of coordination with providing tension on the adjuster piece, using a tool like a screwdriver or long hex key with one hand while I tighten the T-nut screws with the other hand. Now, it is just a simple twist of a knob to adjust the tension, allowing for easy fine-tuning.

El tensor es fácil de instalar, el cual lo instalé en mi impresora Ender 3D pro, mismo que me ayudó a que mis proyectos tuvieran más precisión al momento de la impresión

Bought for my ender 3. Fit perfect and works as intended.

I bought this without really reading the description closely enough. The x-axis is part is nice and is working well. The Y-axis part will not work for my Ender 3 pro. (mine has 4040 extrusion and this is made for a 2040 extrusion for the Y-axis) The parts are decent though. The blue anodization sort of matches the blue colors of the Biqu bed plate but not really. It sort of matches the color of the plastic that I put in the aluminum extrusion to fill the void but not really. I wish the color were just a little darker.That being said, the tensioner works well. I can strum the belt like a guitar string which is great. I get to adjust it with ease. Unfortunately, I have had house guests who turn the knob not knowing what they are doing. (which blew my mind) Making it easy to adjust your belts is handy until someone who has no idea what they are doing turns it randomly. (this may only be something only I have to worry about and only specifically when I have a specific guest at the house, most people know better)I am giving the Y-axis adjuster to my son who has the original Ender 3 and I am keeping the X-axis adjuster on my printer since the Creality one that I ordered will not work well with my linear rails. The Creality y-axis adjuster will be on my printer soon though.I took off one star and maybe unfairly because I was upset that I didn't read the description well enough. I needed to give it four stars though because the X-axis works really well and is staying on the printer.

The new belt tensioner has given me just the perfect tension for the X-axis to my Ender 3v2.
