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

Springs are unusable with v2 glass bed. They will not compress small enough to fit under the hot end. The feed tub caused a feed clog and wasted tip. Ive never had this issue and day 1 with the upgrade kit everything got screwed up. I ended up only using the feed mechanism and some connectors. The rest either wasnt compatible with v2 or caused more issues than its worth.

Since installing Ive had more feed issues. Upgraded bed springs are a definite plus. I would recommend the bed spring upgrade to everyone but not so much the feeder

Worked great, installed easily.

This is a great upgrade for the Ender3. It’s not difficult to install but the directions aren’t as clear as I’d like. If you have the stock plastic set this will be a welcome change.

Would have gave 5 stars but u have to cut a little bit off the spring or u will have binding issues. Not a big deal but does require modification. Over all quality very nice.

Was extremely east to install and worked significantly better than the stock one.

Very easy upgrade...

This is an inexpensive and great upgrade to my CR-10. This is the only upgrade Ive done to my 3D printer. The metal construction is much better than the plastic OEM one that came with printer.

Maybe my kit was missing a piece, but the machine screw used to secure the lever of the filament drive was too short to properly secure it on my Ender 5+. I had to purchase another 20mm-long screw to assemble this properly, so my printer remained disassembled for a few days while I waited for that part to come in.

The springs are wayyyy too long for my ender 3 pro. I tightened them as far as they could go, and the nozzle still scrapes the bed. The extruder is nice but disappointed in the springs.
