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 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.

Simple review really. Recently bought an Ender 5 and had been having problems with the extruder from day one. could load the filament smootlhy, gear was really grinding the filament down and the plastic handle just didint feel like it would last long. Purchased this alminium extruder and everything has been perfect, easy to feed filament through, feel very sturdy and worked first time with esay to fit instructions.

It's obviously an improvement over the stock plastic extruder, which was starting to wear out due to filament abrasion. Note that this unit does place the filament hole even closer to the z-axis leadscrew although it doesn't quite touch, so sleeving the leadscrew to prevent grease contamination of the filament might be a good idea (I used a small piece of the plastic tubing it came packed in with the original printer kit. You do need to put two small screws in to hold the spring - the plastic stock extruder has locating pins for this. Two of the small countersunk screws seem to be best as the heads engage with the spring nicely to hold it stably in place. I used the existing gear and idler from the stock extruder rather than the ones supplied, since they seemed identical. Giving it 4 stars only because showing all pics with the stepper included is misleading some purchasers. I didn't expect or need the stepper but it should be clearer what's actually being supplied. Note that you do also get an angle bracket for mounting a stepper - not needed for the Ender 3 since its obviously already mounted.

Good product. Made a big difference to the print quality.

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 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.

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.

Plug and play parfait

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!!!

Buena calidad, funciona perfecto en mi Ender 3 pro.
