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)

This is a very nice upgrade kit for your printer. The red anodized aluminum leveling nuts are very easy to operate and definitely better than the plastic ones which probably come with your printer. They are not crusty in the threads so the screw on easily. As they say the springs are a bit larger than those which come with Ender series printers, so you will have to address that. The silicone bed spacers to used as replacements for your springs are fairly dense but have enough spring to them to be good at shock absorbing and absorbing some pressure. The nozzles all look to be fairly well made, although it looks like some may not be cut of level on the extrusion end. My eyes arent so good and I dont have any magnification to inspect them closer. So they are the only potentially disappointing aspect of the kit.

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!

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

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

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.

Using on an Ender 3 Neo. Swapped out the old plastic bed adjustment knobs for these aluminum ones. Silicone spacers hold the bed level longer than springs in my experience. Good value for the price!

The knobs are pretty big and easy to adjust. There is no market for direction but by now, you should probably already have this all figured out. The anodizing is a nice bright red and not dull like a lot of the cheap parts. The rest of the parts in this kit are also quality. I’m using the springs rather than The spacers o this printer because I don’t have auto leveling but they seem good too so I’d used them when I upgrade.

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.

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.

Love these wheels versus the plastic ones that come on my Ender 3. I do love that the silicon spacers are two different sizes to overcome the bed heater holder/protector. Look great and work great.
