UniTak3D Ender 3 Belt Tensioner X-axis Upgrade Kit 2020 Profile for Ender 3 Pro,Ender 3 V2,CR 10,CR 10S,Tronxy X3 3D Printers（Black）

For the first 30 minutes, when trying to install this, I was absolutely LIVID! There was one video on YouTube that I could find that covered how to install these and, honestly, they AREN'T difficult to install. The problem I encountered was that, when removing the L-brackets on the pulleys, there was nothing to stabilize the Z-axis support columns! What the hell?! Then, I discovered something that irritates me to no end: I was missing the four M5x20 bolts that screw into the X-axis crossbars! Did Creality assume that, because the L-brackets were there and the corners seemed solid, they didn't need to add them or did they simply forget? I'll never know. Fortunately, I already had the necessary bolts on hand. In addition, I recycled the L-brackets by using the black stock bolt to adhere it to the Z-axis support column like it used to be, added an M4 T-nut on the second-highest rail, and used that to reinforce the corners even more.First, if you're an E5+ owner like me, my condolences on your purchase. Second, if you encounter the same problem as me, check to see if your printer is missing those M5x20 screws. If they are, and you haven't already purchased extra hardware, I suggest you do so ASAP. You never know when you'll need it, like I did.M3-M5 T-nuts: https://www.amazon.com/gp/product/B08CHJMWP5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1M3-M5 bolts/nuts: https://www.amazon.com/gp/product/B073SW4S6C/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1M3 M4 M5 M6 M8 M10 Stainless Steel Washers:https://www.amazon.com/gp/product/B08JC7FSCV/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

Solid and well built. Don’t hesitate if you want it, it’s so much easier than messing with the Allen wrench adjusting.

The Biqu B1 comes with a tension knob for Y but not X and I had some trouble getting tension set properly when I first got started so I started looking for a better adjustment option and this fit the bill. It’s a little fiddly to get it on straight and snug but it’s completely doable.

I purchased for my ender 3 V2 Neo, assuming that it was compatible with the normal ender 3 V2. The X axis extrusion is different and this did not fit; it is missing the slots on the left and right of the extrusion.

This part is required for the printer upgrade of adding linear rails. It bolted right up. Zero issues.

Easy to install and holds belt tension effectively

This tensioner ends up being in the way and collides with my x gantry plate unfortunately

I purchased this for my Ender 3 Max and is a perfect fit. Extremely easy to install and works perfect. I would definitely recommend.

Makkelijk te monteren product.

... Mais qui ne sera pas nécessaire pour le manuel qui sais jongler avec ses outils .

product is as described. Tightens my belt with hot end to prevent wobble like a charm. Fits my cr10 s5 perfectly and it looks like it would fit on my ender 3 pro as well.quick shipping.

One where broken on arrival on the plastic knob.But the parts are really good on my sovol sv05.Use them for y axis on the ender 5 clone.

Système de tendeur parfaitement adapter a la ender 3 pro et a la ender 3 max, design simple et solide, montage rapide rien a dire, toute mes imprimantes en son équipé, ne se détend pas avec les vibrations, avant chaque impression un petit contrôle de tension est rapide et ne fait pas de mal, surtout que par rapport a celui d'origine il y en a pour moins de 1 seconde a ajuster la tension je recommande tranquille
