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)

These are great. The springs that came stock on my Ender 5 Pro had worn out a bit, and the ones on my Neptune X were pathetic to begin with. I replaced them both with these. I like the size of the tuning handle better and that they are metal too. A very worthy upgrade!!

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.

The springs that came with my Ender 3 V2 Neo are more robust than these replacement springs. The silicon column mounts are not an improvement. I do like the large, aluminum nobs but they do not lock in place when adjusted. These move while the printer is working. It is clear that the bed leveling system on my printer can be improved but this is not the way.

Got these for the silicone spacers to make life easier when leveling our Ender 3 Max Neo, and they work great! they make the bed super solid and were painless to swap out. I like the metal wheels included because they have nice grip and are lighter than the stock plastic wheel. Only by a couple grams, but hey, every bit counts. Going to get more of these as we expand our Ender selection

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!

This is a good kit with the MK8 nozzles and silicone spacers that most bed slingers can benefit from. The red wheels are just a bonus and in my opinion dont improve anything but looks. But this kit is the same price as a pack of the silicone spacers I got a couple of years ago for my first printer so great value overall.
