YOOPAI Metal Leveling Nuts and Springs Nozzles Heatbed Silicone Leveling Column Mounts Hand Twist Upgraded Set for Ender 3/3 V2/Ender 3 Neo/Ender 3 S1 Pro/Ender 5 Plus/CR 10 Series 3D Printer (4Pcs)

I recently picked up a used (Amazon Return) Ender-3 and have been upgrading it. The stock bed springs leave something to be desired. The spring rate is very low and I noticed the bed had a lot of wobble and movement while printing. This kit comes with stronger springs and silicone mounts. I decided to try the more solid silicone mounts first, and they work great. I have not tried the springs from this kit as the silicone mounts worked so well, but I do have concerns with my particular printer. When levelling my bed I noticed that it sits very low to the mounting plate, which means that the springs would be compressed a lot. Looking at the springs, its possible they would not work on my unit. Its possible the coils would bind before I could get the bed leveled. The metal bed leveling knobs included in this kit are a nice upgrade. The stock ones were hard to turn because they were so small that the bed got in the way. That being said, these knobs could also be 10-15% larger. The back knobs are still very hard to get at. They also do not have the labeling on them to tell you which way to turn them to raise/lower the bed. Once you realize the screw is upside-down, so lefty-losey (Raise Bed) righty-tighty (Lower Bed), it is easy to remember but would still be nice to have the labelling. The hotend that is on my printer is not the stock one. The person that owned it before me upgraded it. This means the included nozzles are not the same type as my printer uses. However, they will work in my Anycubic Mega X. They are going in its extra nozzles bin. For the price, this is a pretty good kit. A stock Ender can use all the parts and the choice between the spring mounted or silicone mounted bed is nice.

I installed the metal leveling knobs and springs on an Ender 3 Pro. I like that the original knobs had the up/down arrows on them, but its not hard to remember which way to turn them. The metal knobs are roughly the same size, but look and feel better. The threaded area of the metal knobs needs to be a little taller, as it is the knobs are very close to the carriage and sometimes rub it when youre adjusting the bed. Its not a big issue and you could add a washer to space it out a little more, but itd be nice if they added a little length there. I like swapping to the upgraded springs and have used these on any printer with the cheaper silver ones. With the upgraded ones I get more consistent bed leveling that seems to hold longer. Theyre a simple, cheap upgrade that improves print quality some and makes maintenance and tuning easier. I havent used the silicone spacers yet, but Im planning to use them on a CR-10 Mini that Im adding ABL to. My hope is that the silcone spacers will give more stability than the springs, but still allow for some manual adjustment, if needed. I think this is a good upgrade set and I like that you have options for the bed spring upgrade. Especially since you can use them to upgrade the springs on two machines, like Im planning to do. If they extended the threaded area of the knobs then it would be a 5 star set.

Works as expected, I just have some slight issues with one of my screws moving by itself but that is a known issue that I need to get some lock nuts to fix. Makes turning some of the bed leveling sides easier than before but at the same time one of the corners is a little harder to turn because of the limited area under the heater bed. Overall though these work as they should with no issues, all the issues I am having have to do with the machine itself rather than these not working properly.

The Bigger wheels are much needed. Springs are definitely an upgrade if you are looking at a middle between stock springs and silicon spacers.

YOOPAI Metal Leveling Nuts and Springs Nozzles Heatbed Silicone Leveling Column Mounts Hand Twist Upgraded Set for Ender 3/3 V2/Ender 3 Neo/Ender 3 S1 Pro/Ender 5 Plus/CR 10 Series 3D Printer (4Pcs) First impressions: Nice upgrade set of leveling nuts and springs. All of the parts look well made. Installation/setup: Follow instructions to install and adjust. Final thoughts: I’m new to 3d printing and I have no idea if this helps or not. I have to assume it does, it seems to work well. The ones that came on my second hand Ender 3 pro were worn from use and I got these to replace them. ⭐️1 star - I dont recommend it at all, poor quality. ⭐️⭐️ 2 stars - I dont recommend it, it has multiple faults, or a very high price. ⭐️⭐️⭐️ 3 stars - Its passable, It has some faults but the quality is ok for what it is. ⭐️⭐️⭐️⭐️ 4 stars - Product quite acceptable, it does what it promises. ⭐️⭐️⭐️⭐️⭐️ 5 stars - Product that I totally recommend.

I was having trouble with one of my original plastic adjusters just not staying set. This kit has solved that problem. I love the metal leveling nuts they hold much better.

these work very well and were an easy swap - not sure how they want me to judge print quality based on these parts - but i do have really good quality and it works well.

Used the rubber stands instead of the springs because i was tired of constantly having to adjust the springs which would always lose tension or have to be adjusted. The bundle itself is more then worth the price, including extra nozzles, springs, upgraded knobs and the rubber stands!

These are great replacement adjustment knobs

The product appears to offer good value for its price. The leveling wheels are robustly constructed, entirely made of metal and have a superior texture on the edges that makes them easy to hold and turn. It would have been even better if they were labeled for up and down. The upgraded springs that come with the kit seem to be of good quality and slightly stiffer than the original Ender 3 spring, which is good. Nonetheless, the 4 included silicone spacers may work better to dampen vibrations more effectively, yielding superior print quality with less salmon skinning in Y. The silicone spacers are well-made, with one of them being shorter to allow room for the heat beds plastic strain relief. The 4 included nozzles are satisfactory but unremarkable, although it is always useful to have extra nozzles.
