Creality Official Ender 3 Linear Rail Kit X-axis Rail Guide MGN12C 12.6" Length with Mount Bracket Support Sprite Pro kit Compatible with Creality Ender3 Ender 3 Pro Ender 3 V2 3D Printers

This was an easy product to install if you’ve got experience tinkering with your Ender. Instructions are the usual tiny print, nebulous, and ambiguous, like all Creality products. This product is VERY ambiguous as to whether it works with the Sprite and/or Sprite Pro Extruder out of the box. I’m here to tell you that it is natively designed to ONLY work with the Pro model as packaged. I have a non-Pro model Sprite on my Ender 3 V2 and was able to make it work only by swapping the hotend cover with the hotend cover of my mothballed Ender 3 Pro which includes the fans. Not a big deal but the non-Pro Sprite is oriented differently than the Pro and you actually need to search Thingiverse for the bracket required to attach to the linear rail. I printed it out of PETG and used some spare hex screws to attach it and everything works perfectly. But isn’t that what working on an Ender is really all about? I have an A1 and an A1 mini now which leaves my E3v2 in the dust, but I’m doing a lot to keep it still relevant, as it still prints in high quality, just slower. I attached photos of the white PETG bracket I printed to adapt the linear rails and the Pro hotend cover and fans. It’s also housing a Spider hotend and cartridge thermistor so with this setup I can reliably print about 3x faster than my old stock setup. Cuts and Orcaslicer work great with the printer but I’m still pushing the limits. It’s really hard for me to let this E3v2 go….

Buying this i was scared for what I would receive, considering Creality and all. I was blown away with the colored paper instructions and how easy it was to install! They gave me lube and it was already prelubed too! Install took less than an hour! Way to go! I've heard that you should probably get y axis over and x axis upgrade, but I digress.

In retrospect I wish I sourced my own rail and parts but when you're a noob this is the kit to go with. It works well, it's just that self sourcing you can get an MGN12H instead of 12c, and a 320mm rail instead of 300 Insures you don't lose any print volume.So I don't fault the kit, but don't get the kit, if that makes sense.

Instructions aren't entirely clear but other than that it all went well. It needs to travel and be lubricated enough to eliminate the initial noise but afterwards it's pretty quiet. Everything fit as it should, didn't have to change any values in the printer other than z offset of course.

The linear rail arrived with a large gash, suspecting quality control should have seen this issue before allowing it to be shipped and sold to a customer but needless to say creality reached out and offered to send me a replacement. Thank you for great product and good service. Easy replacement and no hassle fast shipment. Will definitely purchase again.

Install went well and made prints alot nicer

This is a set of rails for variations of the ender 3. Note that the hotend adapter plate is the (seemingly) only difference between the two variations-- make sure you select the correct one. While you may save some money buying these components separately, if all you are doing is looking to upgrade your printer with the linear rail (much much better than the default rubber rollers which break down over time) this will work perfect. Creality stands behind their products so it's a safe bet if you need just enough to replace the rail for the upgrade and nothing more. I found no issues with mine (other than I selected the wrong one) but hey, I have a 3D printer, I can print the adapter bracket for the rails. I recommend it!

The “closet roller” wheels typically used on the lower-level 3d printers are functional, but also the source of many problems. They take up lots of room. And they are difficult to adjust and keep adjusted. Replacing the motion system with linear rails creates a more constrained system that keeps everything more aligned and frictionless. Recommended
