Redrex Ender 3 Upgraded Aluminum Bowden Extruder with 40 Teeth MK8 Drive Gear for Creality Ender 3 V2,Ender 3 Pro,CR-10 Series and other Reprap Prusa 3D Printers

I purchased this to replace the broken plastic extruder on my CR-10 and was essentially just looking to have the machine back in action again. This arrived complete with a number of accessory parts including a much stronger bracket than that which was originally supplied. The pieces went together well and were an exact fit for the machine. I hadn't particularly purchased this as an upgrade but the supplied parts - especially the sharper 'cog' have really made the machine feel like new. This has given my prints a real quality boost which was unexpected and I'd certainly underestimated the difference that this would make. This is a really good kit at a very good price. Buy one.

I thought whilst I needed to replace the bowden tube on my Ender-3, that I'd also upgrade the extruder to something more durable, especially since my wood PLA was starting to wear away a notch into the plastic extruder. This was fairly easy to install, and comes with replacement parts for the extruder and gear. The new extruder seem to be good quality and looks nice. My only tip for people looking to buy this is to not overtighten the screws when installing this, as it's very easy to strip the threads.

I bought a metal extruder for my ender 3 after my plastic one began to fall apart. I had nothing but problems with the metal extruder. I tried everything to figure out what the under extrusion problems were until after a month or trying and failing I bought this extruder in a fit of desperation, hoping that this higher reviewed one was the solution. This extruder immediately fixed the problem. Easy to install, the instructions were handy to jog my memory on what goes where (though if this is your first time fitting an extruder I recommend a YouTube video) and after it was installed it fixed all my problems. I'm very happy.

This extruder is well build. It was easy to install. It feels strong so hopefully won't break like my stock one. If you are using this on a mixing 3d Printer then you'll need to make sure all your extruders can run on the same ESteps as you can only have one setting. This is a firmware issue and not related to the unit. I put this on a Geeetech A10M which has two extruders. I had to set the Esteps to 95. It's not skipped or slipped. The prints are coming out just as good as the original extruder. I have noticed a little less stringing with this extruder.

The Redrex Aluminium Bowden extruder upgrade is a really in-expensive and straight forward upgrade from the stock plastic extruder that comes on the Ender 3d Pro, which was the printer I bought this to fit. It`s red powder coat looks cool too and breaks up the black. Please note this kit is upgrade for the extruder part of the motor and does not come with a motor. It came with clear instructions and can be fitted using the tools that already came with the Ender 3d pro so no extra equipment required. It took about half an hour to remove the old one and fit this one. there was only I snag. The feeder gear on my motor is pressed on, unlike older ones that are held in place by a grub screw on a flat surface, so it could not be slid off so I did the upgrade but did not use the brass gear supplied with it nor did I need the metal bracket on my printer. the filament outlet on this part is also upgraded from brass to steel which should also reduce wear and friction. The plastic extruders are known to wear quite quickly and on occasion break when the lever is compressed to release the filament, this upgrade is sturdy and eliminates the chance of that happening all in all a good upgrade that will only enhance future printing.

I upgraded to this extruder within my very first month of printing with my new Ender-3. My "Old" plastic extruder had a huge groove formed from friction with only 1kg of pla (my first Kg). Anyhow, with this new extruder I am currently printing non stop PLA, PETG and TPU with no issues whatsoever. As a plus for me is that it was so easy to install and no calibration of my esteps was necessary (similar gear system with original). Pretty much the perfect extruder at least early on and a MUST upgrade to the plastic one from the get go.

Fantastic investment. The stock unit is plastic, and brittle. I snapped mine from changing filaments. Not only does this come with all replacement parts needed, it also provided an uprated spring. Fit and finish is perfect, nice hard anodized finish adds some colour to an otherwise all black unit. Installation is a bit fiddly but follow the images in the photos above and it's easy enough! Thoroughly pleased - having had 5 failed prints, installed this without changing any settings, and its back to how it should be.

It seems of a reasonable build quality overall. One problem I have is that the spring is held on by a screw in each side. The spring fits over the screw. However, unless you leave the screw loose on one side, the spring will only fit over the head of the screw, and that's not enough to keep the spring in place. I think I can fix this by padding the head with a couple of M3 nuts, but you shouldn't have to do that. I would also like to have seen included in the pack a hex wrench for either the gear or the bolts (or ideally both), but again this isn't a show stopper. Seems to work OK with a reasonable pull on the filament. Not an upgrade but an OK replacement for the stock extruder on my CR-10s.

Werkt goed, let op er is een set die meer onderdelen bevat en goedkoper is

L'ho comprato per aggiornare il mio clone di prusa. Stó montando un estrusore tipo bowden con hotend V6; usato con il motore originale, facilissimo da montare, le istruzioni sono delle foto passo passo... quindi impossibile sbagliare. È tutto in alluminio, robusto e veramente ben lavorato e rifinito. Per il prezzo pagato e la velocità con cui l'ho ricevuto credo di aver pagato il giusto. Consigliatissimo come ricambio o come ho fatto io per upgrade. Comprato dal venditore Redrex3d. Spero di essere stato utile.

S'installe très bien sur une Discoeasy200 Dagoma en remplacement de l'extrudeur d'origine. Permet d'avoir le levier côté arrivée filament (plus pratique), fonctionne avec pression ressort au minimum. Ai dû raccourcir de 2 mm le sommet du levier qui frottait légèrement sous le plateau (facile, quelques coups de lime). Embellit mon imprimante, extrudeur parfait pour mon usage.

Really good quality of the parts! Also looks very nice. Please nore that its recommended to put some nutlock fluid on the screws for the spring. Fast delivery! I totally recommend this seller! 5 stars!!!

Top Qualität, passt perfekt auch für meinen Elegoo Neptune 2 Drucker.
