3D Printer Kit with Aluminum Ender 3 Extruder Upgraded, Compression Die Springs for Bed Leveling, Metal Hand Twist Leveling Nut Suit for Ender 3 Pro/5/5 Pro, CR-10 Series/10V2/20/20 Pro

Great product! Easy install and great quality.

While much of the installation is obvious, a few items were not and documentation was lacking. I could not determine how to install the new drive gear properly. The bed leveler wheels need deeper offsets to be most useful.

Springs are too long

Awesome addition. I bought mostly for the tighter springs, but when i went to replace the extruder covers i noticed that the plastic pieces i was replacing were cracked and about to break! highly recommend these parts. note: you will have to move your Z-stop up a bit due to the change in springs and wheels.

very good quality and good upgrade for my ender 3 pro

These are great springs, still have to use washers on the front to compensate for it being a cantilever tipping a bit forward, how ever these keep the bed level longer. The extruder rocks, make sure you have the ability to replace the Bowden tube and tube nuts when replacing this extruder. The all metal wheel nuts are awesome and hold in place better than the plastic oe ones.

I was really pleased with this purchase. These leveling nuts are not a cheap plastic rather, a nice aluminum. The extruder kit is also a nice hard all metal, came with all the mounting pieces, including an extrusion gear and bearing. Overall quality is great and amazing value.

Nice new part for my new printer.

Everything was as expected but it was missing one of the bed leveling screws it just came with one

These work much better than the stock pieces. But they still come loose on their own sometimes.
