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

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

I really like the look of the bright red aluminum adjustment wheels. It matches the red fittings on my Ender 5. The fit and finish of the materials in this kit are great quality, and everything fit as expected. On of my biggest frustrations with the ender 5 is adjustability of the leveling table. I used the bushings and adjustment wheels from this kit, and opted not to use the new springs. I found the table much easier to level with much less adjustment. That was a really great surprise, and makes this kit worth the upgrade. The bushings are supposed to provide a more secure adjustment, so hopefully less correction will be required down the road. Nothing is more frustrating than to discover a print was ruined, because the table fell out of level, and you print overnight. So far I am impressed with this kit.

Not sure why nozzles are included in this set, but hey, what a bonus! I always prefer the red aluminum leveling nuts over the black plastic versions. They wont improve print quality or have any significant impact on your prints but they look great. They are also easier to adjust. The tighter springs will help keep your bed level for longer periods and will make adjustments easier. This will have a positive impact on the quality of your prints because everyone knows the secret to a good print is a good first layer, and a level bed is necessary for a good first layer! The silicone mounts are meant to replace the springs when your printer has an auto leveler such as a BL/CR Touch or an EZ-ABL (or equivalent). You will install these, tram your bed and then let the auto leveler do its thing.

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 just have to say, wow, what a noticeable difference getting rid of the springs on my ender! Comes with stiffer springs and silicone spring replacements. Easy to install and comparable in price to many other options.

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.

Decent upgrade.

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 ordered this accessory kit to test the silicone leveling spacers and they work great on my Ender3 V2 Neo. The bed is really rigid now. These spacers will work on almost any Creality Ender 3 printer except for the Ender 3 S1. The S1 requires the spacers to be the same size due to a different design for the bed strain relief. Three of the spacers measure 18mm and one is 16mm. The aluminum bed adjusters look awesome and add a nice custom touch to the printer. The nozzles are the standard .4 brass and work like stock ones. Great kit.
