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

Nice solid construction fitted very easly well worth the price. yet to test my printer with it fitted but belts are nicely tensioned.

Nice and easy to install, literally took about 5 minutes. nice that it comes with a toothed roller for better grip. Well constructed and does exactly what it needs to do.

Not a huge amount to say about this. It fit easily onto my Ender 3 Pro and takes the faff out of tensioning the belt. Well made for the price.

I purchased this X-axis belt tensioner for my Creality Ender 3 Pro as the belt was loose and my prints were looking stretched. This was very easy to fit. I just loosened the belt, undid the pulley assembly and replaced it with the belt tensioner before reattaching the belt. The belt tensioner didn't come with instructions but fitting was easy to work out. The belt was easy to tension. I tried a few test prints, such as a 2mm x 2mm x 2mm cube to test the dimensions and the improvements made was instant.

Was having tension issues on my ender 5 plus, screws slipping as i was trying to adjust the tension with the supplied tensioner. Bought 2 of these and all my issues were solved and my printer runs PERFECT. Fitted both in about 10 minutes, very easy install too. Great product and have ordered 3 more for my other printers.

I have tried two adjustable X-axis belt tensioners in as many days, and I'm back to using the original Creality one. This one has a rather tacky plastic roller, with no sign of a bearing. Unfortunately, it is not possible to use the roller from the original tensioner. In comparison with this, the Creality one is brilliant and less prone to accidental misadjustment.

Bought this and an X-axis one for a Creality CR20 printer (essentially an Ender3 with a box base where the electronics and PSU sit). X-Axis fits fine, but this Y-Axis one fouls on the box base. Ironically, if it was made out of metal the same thickness as the original, it would have fit just fine, but its higher quality components and thicker metal parts seem to have backfired this time around. Other people have mentioned the tiny, weak looking screws used to fasten the sides and the front, but because they're under compression, they will likely be fine in use. I have also heard about cog wobble but couldn't verify this as I couldn't install it. To be able to fit on a CR-20, the right-side part (as seen from the front of the printer when installed) needs to be trimmed at the bottom, to fit the limited clearance. There's plenty of available material available, and it should be very straightforward. I plan on doing this at some stage, but need the printer operational so it's a job for another day.

found it a fiddle to fit. once fitted did the job ok

Makkelijk te monteren product.

Passt perfekt am CR10S PRO. Auf dem Foto seht ihr den gespannten Zustand - es ist noch reichlich Spiel zum nachspannen. Das ganze Teil ist solide und ordentlich verarbeitet. Das die Zahnschreibe Spiel auf der Achse (Schraube) hat, stört nicht. Klare Kaufempfehlung von mir!

Produit qui semble robuste, très facile à monter sur l'imprimante, permet de bien régler la tension de la courroie. Pour le prix, rien a redire

Sur une Ender 3 Pro j'avais la courroie des X qui se détendait régulièrement avec du coup des trous dans le plan XY plus très ronds. Avec ce tendeur facile à installer en qqes minutes on peut retendre si besoin très rapidement et régulièrement (encore que depuis son installation la courroie ne se détend plus). Produit de qualité vraiment correcte.

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.
