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)

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!

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.

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.

Upgrade Set Review Introduction: I upgraded my 3D printer with the YOOPAI Metal Leveling Upgrade Set, specifically designed for Ender 3/3 V2/Ender 3 Neo/Ender 3 S1 Pro/Ender 5 Plus/CR 10 Series. This set includes metal leveling nuts and springs, silicone leveling column mounts, and a convenient hand twist design. The silicone leveling column mounts included in this set further enhance the stability of the printers heatbed. They effectively absorb vibrations and reduce the impact of external disturbances, resulting in smoother prints with reduced artifacts. The improved stability also helps prevent print failures caused by unlevel or wobbly beds. I highly recommend these as a simple upgrade to your 3d printer.

I’ve got 5 printers and have ordered kits like this for at least 3 now. The spacers are so nice. Worth every penny

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.
