The media could not be loaded.  I have had my ender 3v2 for a little over a month now. When i set it all up I could tell that this new venture would be a tedious one. Boy how I was right. After some time my printer started to run into the print even though I had just leveled the bed and compensated with Z offset. The tension springs that came with the machine allowed the knobs to get loose during my prints. It was VERY frustrating. 12 hours of work ruined. I did attempt to solve the issue by taking the springs off to see the problem. No sings of trouble I began to reassemble the bed. They were so easy to take off but to put the springs back on was a very trying moment! These upgrades hold the position firm. I already see the difference in the print I have started. Assemble was stupid easy. It’s worth saying that the first bed leveling process was more challenging that the springs.. However, I have no complaints if these need very little upkeep because the hold the adjustments with a firm grip.

These do not fit the ender 3 pro, Voxelab Aquila, or the ender 5 plus correctly. The original wheels have a bump on the upper side to help with bed adjustment. These wheels are completely flat on both sides and do not adjust enough to make the bed level. The silicone/rubber “springs” it comes with are shorter then any bed spring that comes with 3dprinters so those will never work, not sure what that’s about..But even with the original bed springs, the wheels just don’t work.. you can’t adjust the bed up or down enough to get it leveled correctly..These replacement wheels are made well, and very sturdy, but they need to be revised a bit to be more OEM fitting so they actually work.. as they are they’re useless.Revise the product so that they’re the same shape as the oem wheels, and it’ll be a 5 star product. Right now it’s a 3

The leveling nuts didn't fit an Ender 3 Max. They wouldn't thread on very far before seizing, but I didn't buy this for the nuts. Just buyer beware if that's why you are buying this set.But what I really wanted was the silicone spacer spring-replacements. These are simply AWESOME!! I went from having to relevel EVERYTHING after each print--to having my BLTouch show that the distances to the bed are nearly exactly the SAME after each print!!I saw people saying to try these. I bought a set of after-market leveling springs at the same time, but it looks like I'll never be using them. They'll just be spares. These silicone spacers DO THE JOB AMAZINGLY! I couldn't be happier with this purchase. These things make me feel literally joyful!I don't know about printers other than the Ender 3 Max, but if you have one of these, you'll be VERY HAPPY replacing the crappy original springs with these--I PROMISE.Best addition to my printer YET!! :D

These are very nice. My E3 V2 required 4 of the longer supports. They are perfect for this purpose. I set the bed with the left front corner and then did 3 counter clockwise revolutions around the bed with a feeler gage and the bed has not moved in the last three weeks. The wheels that came with the kit did not thread on the existing studs reliably, they seemed too loose, i.e. a tad larger in diameter than correct. I just used the original leveling wheels and we were good to go. You get amazing fine control with this system and nothing moves once you are done.

The spacers are useful and better than the stock springs, I'm not sure why they provide (2) sets. Perhaps these will wear out? I put the wheels on my printer and removed them a week later. The extra weight to the Y axis is detrimental at high print speeds and the wheels simply don't have a good "feel" to them. The stock wheels (Ender 3 Pro V2) offer much better grip and function.

The wheels are a nice quality. The blue paint is a bit thick and overkill. These should of been anodized not painted... Some of the paint is in the threads so do yourself a favor and run a screw thru it before trying to install. Note that a previous review started the wheels were flat to on both sides. My order there is clearly a hub that protrudes out. This should go against the aluminum plate. The silicone springs work well. I am not convinced the ender 3 Pro heated bed stain relief is 2mm thick though. I might measure it up and print a washer to fill the extra space. Still working great though as installed.

Works well. The rubber supports hold the build surface much more rigidly as compared to the springs. I also added lock nuts to the underside of the adjustment wheels so nothing moves on those longer print periods.The adjustment wheels are aluminum and well made. Good value for the money.

There was certainly some aggravating aspects to these. Same size as the standard ones the CR-10 came with, which is in the description. Look cool. But getting them on the machine was difficult at best. Almost have to force them on. After that I tried to level the bed. That didn't hold up. Leveled, tried to print, couldn't get the filament to make contact with the build plate. Tired this several times. Each time failed. Switched back to the originals, back to good prints. I wouldn't waste the money or capital.
