Y-axis MGN12H Linear Rail Guide Kit 3.0 for Ender 3 V2 and V2 Neo 3D Printers Upgrade Include Heated Bed Support Plate and Custom 4020 Profile Accessories from ChowThink

Nice for the Y axis, no more adjusting thee cam offsets on the wheels!

The new bed height is so low the leveling wheels are practically touching the base and extremely cumbersome to adjust now being against the base. I may abandon this company's kit and go with another. This was installed on my Creality Ender 3 NEO's Y axis only

I have purchased both X and Y axis linear kits from ChowThink Instructions are clear.I have installed both upgrades successfully.I recommend the Seller, keep the quality same!

The media could not be loaded.  I have a Ender 3 v2 from it's first release, so maybe the hardware is incompatible but, the bracket screws get in the way and stops the bearings from moving stopping me from completing my upgrade.

Love this kit, really easy to install and gives an extra 20mm more Z height, but the included rail was quite loose and wobbly. Swapped it out for a different rail and it's perfect now

If you buy the Y-axis linear rail kit, it will work (although your bed might not be any more stable than before - mine has some Y-axis rotation now that it didn’t have before). But you will need to buy the Z-axis kit as well. And buy a second Z-Stepper. I haven’t gotten further down this dependency path yet, but yeah.EDIT: This Y axis kit sucks. The bearing isn’t tight enough, so I have tons of wobble on that axis, causing warbly prints.

Turtle description gives you most of the info but to actually screw in the y-axis profile you need four M5 X 40 the ones that are included with the under 3v2 are m5 x 45But they will give you new screws for your 3D printer bed which you already have why not spend 50 cents to put in the proper screws
