ENOMAKER Ender 3 Pro/V2 Upgrade Linear Rail Guide Kit Y Axis, MGN12C Bearing Stainless Steel Guideway Slider Improve Speed for Creality 3D Printer

I would recommend buying a larger bearing and replacing the one provided, only because of the sideways load applied to bearing and it wears out quickly. But the fitment and install were great! Would recommend

Everything fit together good. Instructions were crap, the rail slider had play in and I couldn't notice until it was assembled it wasn't enough that I noticed any issues yet but I ended up upgrading to dual rails and returning this. If you're on a budget this is a good option but I would recommend buying 2 rails and printing attachments and you don't have to replace belt or the base.

This single rail y axis "upgrade" makes leveling the bed and keeping it level basically impossible. Needed adjusted before EVERY print for the week I had it installed. Only got worse. The rail is off to the right side and the left side is very unsupported, hence the change in level every print (just probing is enough to throw off tram). It also adds over 10mm under the bed so you will lose that in printable height. Get the double rail (2 small brackets) kind that goes on both sides of the 4040. That one makes the support even more spread out across the entire bed than the original. Way more stable than this garbage. Trust me, Your time and quality of life is worth the price of the extra 300mm rail. The blue is not really that pretty and the finish is terrible, anodized over raw saw cuts, no smoothing. I could've lived with that though as you barely see the parts when installed. NOT RECOMMENDED.

Product title and the description is misleading. This is not for an Ender 3. it is for the three pro or V2. I am going to have to do some modifications on the plate and on my bed to get this to work at that price. I should not have to do that would probably be great for one of those the ball bearings are, and it is quite stable, so buyer beware

First off, the aluminum plate is great and all hardware plus spares are included and correct.Now for the reason for the 1 star review. The linear rail was extremely crunchy and took alot of cleaning and lubrication to get it to work at least somewhat decent. This is by no means my first time taking linear rails apart and tuning them so i know i did it correctly and lost no bearings yet i believe that some were missing. After working on it for longer than I have ever had to on any of the other carriages i finally decided that it was good enough. I installed rail and affixed bed and belt and to my surprise i noticed that the bed could be moved 1/8" after everything was tight. I took everything apart thinking it was something I did and after redoing everything multiple times I found that the carriage is loose on the rail as if the rail is too small allowing for play in a twisting motion rendering this completely unusable and a waist of a day. Very unacceptable. Hope the seller will correct this.
