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

I like the metal upgrade, springs are great, and the twist nuts are cool but the extruder set was missing a bolt. I was able to reuse old bolts that I had, but be aware, you will be one short.

Product was exactly as described, works fantastic. I would recommend anyone having issues with leveling or extruder skips to purchase this kit. Its fantastic

Great quality! Way better than what originally came on the machine

Everything seems to be good quality however the springs were missing in my order.

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

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.

These springs are a serious upgrade over the stock Ender 3 Pro springs! I read a lot of notes saying that the stock springs just didnt have enough tension in them, and after every few print jobs I was having to level the bed again. Not the end of the world, but if something will solve that problem for under 20 bucks, and upgrade the extruder to aluminum, why the heck not go for it? Everything arrived quickly and was neatly packaged. After opening the bag with the bed springs and wheels, I was impressed. The springs are very beefy, the wheels are nicely made and have good grippy teeth on them, which will make fine adjustment much easier, plus the pop of red under the printer is a nice touch. Installation was pretty simple: Unscrew the stock adjustment wheels until they come off the screws. Lift the bed up (being careful not to damage the bed heat wires). Remove old springs. Then I set the rear springs in place and put the bed screws down through them to hold them in place, and then tilted front of the bed down and slipped in the front springs. It was a little awkward to get it all lined up, but nothing too bad at all. After that, I attached the fancy new adjustment wheels. I went around the bed, tightening each corner to around 25%, 50%, then 75%, then finally 100% of the way down. I figured I should tighten them up gradually to keep from twisting the bed or knocking anything too far out of whack. Happy with how things looked, I turned on the printer and hit auto-home, and discovered a problem: Home position now had the nozzle below the print bed! I went back and checked the adjustment wheels and they were cranked down as tight as I could get them. I ended up raising the Z-axis about 2mm and that looked better, so I adjusted the Z-axis stop switch up until it clicked against the bed. Then I fired up the printer again and auto-homed it. Much better! I could see I had a gap now. I dont know if it was the upgraded parts, luck, or what, but leveling was much quicker. I leveled all four corners, then checked the center and it was dead on. After that I went back around the corners to check them all. The front left needed a tiny tweak and everything else was dead-on. The aluminum knobs are super grippy and very easy to make tiny adjustments. The stock plastic wheels werent terrible, but there are definitely better. Ive run 3 or 4 prints since doing the upgrade, and after that batch was done, I checked the level again. Still dead on , right where I left it! Hoping that continues, and things stay exactly where I put them. The extruder upgrade is really nice as well. It went on without any hassle, and feels way better than the cheap plastic included with the Ender 3. (just make sure when you remove the old one that you support the motor - the extruder is what holds it in place and when you remove the last screw, its going to drop!) The thing I like most about it is that its silver so its MUCH easier to see the hole past the gears that you have to get the filament into. That was a huge struggle for me with the black plastic, and with the new silver extruder, you can see exactly where the filament is going and it slipped right in with no trouble at all. I will say that the spring that came with the extruder was bigger and harder to compress than the stock one, and I didnt like the feel of it installed, so I used the stock spring and its been great so far.

I have 4 printers. 2 with a similar red kit and this kit which is the silver ones. The metal extruders seem to be the same or same quality on each however this kit has better springs for the bed. These springs are a little beefier and seem to hold the build plate level a little better. Less micro adjusting needed. I would recommend to get some Capricorn tubing with this kit as well and you should be set

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.

All the components in this kit are well made and easy to install. I installed these on the Creality Ender 3 Pro and they are much better than what came with the printer.
