I bought this alongside my Ender 3 Pro. It was my first printer so I had no idea what I was doing other than people recommended upgrading the extruder and bed springs over the stock options. Installation was pretty simple and it all looks and feels great. If i had to complain, itd be about the length of the springs. Out of the box they were a bit too long for the Ender 3s bed, but a few quick chops with the right tool and I was in business. Better than being too short, I suppose. I saw some similar options that include an upgrade to the bowden tubing, but in my experience this doesnt seem necessary. I recently tried printing with flexible TPU with the stock tubes and had excellent results.

Amazon has a serious counterfeit product problem. After purchasing another of these kits its clear this is a counterfeit kit I received this time from this seller. Who knows if Amazon just grabs knockoffs off the shelf vs legit products or if sellers know theyre selling counterfeit products but this time it appears to be real. Hardware is tarnished and cheapish, fitment is sloppy, having the two side by side makes the knock off obvious. May the odds be ever in your favor.

Picked this package up right after getting an Ender 3 Pro. The all metal extruder feeder is a must to replace the plastic one that quickly wears out and causes problems. For the seriously good price I went ahead and grabbed this kit for the metal knobs and upgraded springs. The knobs are a nice to have and feel better when leveling, but the springs make the surface feel much more stable and give more control when leveling. This is a great value for a few upgrades that should have come out of the box with the Creality Ender 3.

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.

This is a good deal if thats all you are after. After making my purchase I found better deals that included Capricorn tubing, spare nozzles, spare bowden couplers and clips and all sorts of stuff for just a dollar or two more.

Springs warped the print bed.

TLDR: If you indend to go direct drive at some point you should get a dual gear extruder instead of this. Full review: Everything in this kit is useful if you leave your printer as bowden drive. The spring upgrades are nice although I have seen there is now a silicone rubber version which is supposed to be a bit better than the springs. I have not tried those and am happy with the orange springs. The oversize aluminum adjuster wheels are great and better than the smaller plastic ones. The metal extruder works better than the plastic one, however when using in direct drive format it would click because it would let the filament slip through the single gear mechanism. I upgraded it to one of the metal red dual gear extruders instead. I am using the hero me 5 remix of the direct drivinator and it works great on my ender 3.

Everything needed was included, and very easy to install. If you use a glass bed, the Z-axis stop will need to be adjusted up about 3mms

I upgraded these on my Ender 3 Pro to ease maintenance. The stiffer springs are a HUGE improvement over the stock springs and rarely need adjusting now The extruder I saw as insurance knowing that the stock plastic extruder arm is a potential failure point

Crucial upgrade, great quality
