Creality Upgrade Ender 3 Extruder, Ender 3 V2 Upgrades Metal Extruder Aluminum MK8 Bowden Extruder 40 Teeth Drive Gear for Ender 3 Pro/Ender 5 Pro/Ender 5 Plus/CR-10 Series 3D Printer

This kit has the generic Capricorn tubing that creates a thick pasty grease and will clog up your machine and ruin your hot end.

Ok, so I dont have a CR-10 style machine, so it would probably work on there. the primary reason why I got it is that the dimensions should fit a Monoprice select mini V2. It does, but its that stupid spring brings down the kit for me. Apparently, its too damn strong to use and causes the motor to skip. I tried cutting it down, but that still didnt work. I tried using the stock spring form the old extruder kit, but I had no luck since it was not strong enough. the Capricorn tubing works, so no lost points there. The springs arent compatible with my machine, so I cant speak for their performance. If I could find another spring that would fit this kit and not be too tight, then I would recommend this kit to those that have the same printer as me. As it stands, everything else in the kit works, but its obviously geared towards a much more popular printer. Some stuff is transferrable though, so its not a total loss. Also I know that the kit isnt geared towards the Monoprice machines, but it fits a standard NEMA 17 Motor. so anyone who has their extruder hooked up to one (Which should be most of you) should be fine. I just lost the lottery on this one. Edit: Customer support heard my complaints and fully refunded me. Changing my stars from 3 to 4 as customer support really did it for me. Compatibility is still iffy, but Im willing to forgive it for this great level of customer service. Original post above for more context.

This is a perfect all in one kit of all the mandatory upgrades for an Ender 3. Included the bed springs, capricorn tubing, and metal extruder. Also includes upgraded bowden couplers as well plus the coupler lock clips.

Springs are awesome. Line feeder upgrade is awesome. All the extras are awesome. Great price and you will notice the difference.

Replaced the factory extruder on my MonoPrice Mini Delta. Works great.

Good product cheap price

Replaced failed extruder on Monoprice IIIP. Works great. Printed a test piece, looks fine.

Fantastic. It has rescued my printer. Now the PLA feeds well.

Everything went together great, had my printer back uo and running within 15 minutes.

Excellent replacement for the stock extruder and it seems to be legitimate Capricorn tubing.
