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

they help keep my bed level a lot easier

Straightforward to install, would recommend. Consider drilling a hole into the vertical support (left - if facing ender 3) to be able to tighten the X axis rail.

This is a very worthwhile modification, it made my horizontal bar rock solid. The reason I got this was because I could never get the guide wheels on my carriage tight enough to track correctly. I noticed that during bed leveling when there was a lot of movement in the z-axis that the motor side of my horizontal bar would start moving slightly before the other end. This second motor and screw set stopped this problem entirely. They also included some screw stabilizers for both sides of the printers vertical arms which was a nice touch. I did need to very slightly shim the new motor away from the vertical arm because it was binding up a little at the bottom of travel. Another reason I got this was to help support the Sprite Pro Extruder/Print head I added. Not sure if I really needed to but it made sense because of how much bigger and heavier this but of equipment was compared to the original print head the Ender 3 Pro came with. The only reason I didn’t give this a 5 was the need to cut the ends off the carriage mounting screws so it would fit my Ender 3 Pro. I thought they might consider at least putting some shorter screws in the package to eliminate this problem for the future.

I started with stock springs and upgrade to the orange springs. Those were a nice upgrade, but still found myself leveling my bed after a few prints. Saw recommendations to use the silicone mounts and its a much better upgrade. it holds better than the springs and does a great job of keeping the bed level. I dont have to level the bed as much with these mounts. Just remember to use the shorter one on the back left corner.

These rubber cylinders are much better than the springs for keeping the Ender 2 Pros bed level. Before, I seemed to be constantly leveling the print platform but now it seems to keep it level print after print. The red nuts or wheels that came with them are really well made but unfortunately the diameter seems to be too big for the Creality Ender 2 Pro. Had to stay with the original plastic wheel nuts. Thats why the four stars rather than 5. Wuld have been great if they had indicated which of the Creality 3D FDM printers this would not have worked for. But highly reccomend the rubber cylinders, night nad day difference as compared to the original springs. Install is also pretty easy. Am happy I got this, the frustration of bed leveling has decreased substantially.

Put these in and you will hardly ever have to relevel your bed. The wheels are nice but the edges are a bit smooth so your fingers will slip.when tightening them.down some.

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 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

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.

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