Ender 3 Springs, Creality Upgraded 4pcs Red Aluminum Hand Twist Leveling Nut & 4pcs Black Heatbed Silicone Leveling Column Mounts for Ender 3/3 Pro/3v2 3D Printer

This is a great upgrade with some exceptions. You have to level them with some printed leveling blocks before printing unless you get anti backlash nuts then it reduces this to just checking to be sure they are level every so often. Also the supplied upper bearings holders are good but will bind if not aligned correctly I leave mine slightly loose so they go with the flow otherwise I had binding issues over time. With them loose and able to have left/right movement I have had no more issues. Print knobs for the top of Z Screws so you can hand turn both z axis screws for leveling gantry when needed as well. Once printed thro a dab of super glue in the top and screw knobs on.

So I’m rewriting my review. Initially I kept my Z limit switch in the factory position, I was new to 3D printing and didn’t know much about adjusting it. After lowering my Z limit switch a few mm and tightening up the bed screws it really brought this printer to life, now I seldom level my bed, I do check it periodically but it’s never really off by enough to matter. I’ve now added these silicone mounts to 2 different printers and With some fine tuning my prints have came out amazing

The aluminum adjustment rings were quite nice since they were made of solid metal with a nice red sheen but when I screwed it on my ender 3 pro it loved to slide against the metal it was mounted on which was a design flaw which the original mounts did not have. Next time add a spacer between them. You should buy a pack of washers for them.

they help keep my bed level a lot easier

Good quailty and nice fit!! One tip! If you are intending on using a belt in conjunction with this kit, print risers for the motors so that the lead screws will stick up above the top of the stabilizers that come in the kit. That way you have enough rod for the belt pullies to fit on top. Thingiverse has a file for 1cm riser that works perfectly. This picture is without them as I didnt think about it until after I installed it. Now I will have to print them and go back and reinstall. Here is the spacer link(add this to the end of the thingiverse URL right after the .com Amazon may not allow a full link): /thing:5367399 Happy printing!!

Installed on a Creality CR-10S. The knobs are nice and I am using them, but the silicone springs (whatever you would call them) I had to remove as they are too small. Once installed and tightened the bed is too low for you to level it with the nozzle. If you loosen the knobs to raise the bed, by the time its high enough to reach the nozzle the knobs are all loose enough to fall off and the bed wobbles. You could probably get these to work nicely by lowering the z-stop switch a bit, but I have not attempted that.

Working perfectly on my Ender 3. I can not see any printing quality difference after installation...but I believe it can make the printer more stable and reliable.

The spacers fit well and work great, the knows however do not fit and are worthless they will grind the bottom of the bed when tightened , ender 3 v2 neo

Pleasantly surprised to find these are creality springs and knobs, not just knock offs. I put these style knobs and springs (knock off or not) on all my machines. Add a nylon lock nut to the bolt before installing these and youll hardly ever need to level the bed again.

Great quality parts with clear instructions and all of the parts you need! This made my print layers much more accurate. No more banding.
