I bought this kit mostly for the springs.I ended up making some sleeves that go inside the springs because they still didnt want to stay vertical even with the flat ends. They are firmer thought and work nicely. The extruder top was just a bonus, and its really nice. Only drawback there is it should have instructions or at least a diagram. I ended up going back to the stock adjuster wheels. The aluminum ones are made well, but they are too slick imo. The stock ones have better knurling and are lighter weight.

Legit deal. Legit parts. Everything is exactly as described.

This set is a must have for any Ender series printer. The original springs that come with your printer are not that strong which leads the bed to be become unlevel very easy, sometimes even during a single print. I used to have an adjustment wheel left on the counter under my printer because it worked itself loose during the print. This set of springs will take care of mist of the leveling concerns you may face. The wheels themselves arent bad that come toil the printer but the red ones look and feel a lot better. The all metal extruder is well worth the money and time it takes to replace. The original one is plastic with a metal tube for the filament to travel thru. After 6 weeks of daily printing of PPE, the filament, even with a filament guide cut thru the tube and started to cut thru the plastic feeder. This will eliminate that problem all together. You have to be aware that the gasket/screw that holds the boded tube to the extruder is NOT the same one/size as the original plastic one. You will need to use the same size that is attached to your hot end (the other side of the boden tube) Get extras of that as well...... Overall, this is a first paid for upgrade that you should do on your machine. While you are at it, get some extra boded tubes form Capricorn.

Great product! Easy install and great quality.

I’m not even sure where to start on this train wreck… Basically, it’s nothing like what is advertised. Many missing parts, low quality, poorly made leveling nuts and more. The metal on the leveling nuts is pitted and looks more like scrap metal that sat outside for a long time before being spray painted by a 10 year old. This is like going to McDonalds for a Big Mac, but they give you two fries and a chicken nugget with a bite taken out of it. I’ll be contacting the manufacturer directly about this and will leave an update afterwards.

Everything was fine except one of the leveling wheels would go on because of bad threads. Springs are great, extruder seems to be of great quality. Not too worried about the wheel, as it was my least needed thing of the package, but still a little disappointing. Other than that Im very satisfied

Bought it a month ago and worked great, but was disappointed when I noticed extrusion problems after a long (25 hour) print using glow-in-the-dark filament. I know that type of filament is abrasive, but that is the whole point of buying an all-metal extruder assembly. Took apart the extruder to clean it only to find the hole where the filament enters the extruder had worn out completely. Fortunately it is inexpensive to replace, but was disappointed that it didnt last longer. The replacement bed springs and adjustment knobs are working as expected.

The metal extruder is to replace the plastic one that the arm cracked. Warning the z will need to be adjusted as the springs are taller, making the bed higher. Failing to account for that the nozzle will drive into the bed and damage one or both. The bed remains level better after, but be aware to check first.

I havent gotten a chance to see how the extruder works yet, although it seems to be of good quality and installation was easy. The issue I have is that the bed springs are too long for an Ender 3 pro, even though the description says they should be able to fit. I will try to trim them but they are made of very tough metal and are difficult to cut.

installed the extruder upgrade and halfway through the first print the screw that hold the bearing came loose . the aluminum was poorly machined and the screw came out with the threads .... basically its useless .... seller wont respond to inquirey .
