Aluminum Hand Twist Leveling Nut and Hot Bed Die Springs Printer Compression Springs Compatible with 3, Ender 5/5 Plus/Pro, CR-10, CR10S/10S Pro, CR 20 3D Printer (8 Pieces)

If you are going to use this with a Ender 3 with a glass bed, you might have to move the limit switch up a few millimeters. I found the installation to be moderately difficult to pinch these strong springs into the plate, but after that was done, I found that even cranking them all the way down turned out to be not enough to clear the nozzle. I had to raise the limit switch about 2 millimeters for the nozzle to clear the glass bed.After doing that, all is great, and it's extremely stable and solid. MUCH better than stock springs. I don't really care for the aluminum leveling nuts. They are not necessary-- the plastic stock ones are the same diameter and work fine, but the metal ones add a bit of flair if you want that. The important parts of this upgrade are the springs, and they are excellent.If the springs were just a bit shorter they'd be a total drop-in replacement on an Ender 3, but with a minor limit switch raise adjustment, you're in business!

Easy to install and makes a big difference. The stiffer springs keep the bed level for longer and I don’t have to level the bed as often. I still check the bed height after each print but it doesn’t move very much if at all. A cheap and solid upgrade! (Installed on Ender 3 V2)

These wheels are great! I gave them five stars, even though I should knock them down a little for not being as textured as they should be to effectively turn them. They hold position so well with the stiffer springs that I rarely have to adjust my bed anymore. The stock hand wheels on my Ender 3 Pro stripped out after a few prints. I don't expect that to happen with these! Sure wish they were stealthy black, though...

Pretty, but minor design flaw in that the hub is flush with the side of the wheel. There is a Z-Axis Spacer available on Thingiverse that will add space between the side of the wheel and the bottom of the printer base to eliminate the rubbing problem.

Greatly improves the stability of the bed. The much stronger springs ensure that the adjustment wheels don't vibrate loose, and the aluminum wheels are much easier to adjust.

I ordered this to help with consistent leveling for my Ender 3.The springs are WAYY more stout than factory and the knobs are more user friendly than factory ones.That being said, if you have upgraded to a glass bed you’re either going to need to cut these springs down a bit, or find shorter springs.I cranked the knobs all the way down and was unfortunately about 2MM short from the nozzle not dragging.I just switched back to factory springs for now.

Prior to purchase I asked if these would fit the CR10S5 as they are listed as working the CR10. I was told that yes they will work. However they do not fit. I was slow in installing them as my printer has been running nonstop for a few weeks and only now got a chance to test them. The wheels are in fact too large a diameter to fit on the CR10S5 and not collide with the frame.That said the set does come with stronger springs and the wheels are a very nicely machined and finished. My 3 star review is only related to the fit issues not the quality of the parts. Unfortunately for me i waited to long to test them and my return window has closed. Not a big issue are they were relatively cheap and will probably work on another printer someday.

Good grip makes them easy to use. Can level the deck lower than factory. Go ahead and tighten them all the way when you start. Then back off to level. Also, they look cool.
