This is a perfect addition to upgrade your FDM Printers to a linear rail configuration.The carriage slides smoothly and the rail is straight, can't ask for much more!

Review of CNCYEAH MGN12H 1PC Linear Rail Guide 300mm Black Miniature:I've ordered quite a few linear rails and extrusions and unfortunately several have arrived damaged due to poor packaging. However the packaging on this was excellent - in a cardboard box with literally 8 layers of taped bubble wrap and then a sealed plastic bag. No way this is going to get damaged in shipping.The rail itself is super smooth and no "slop". Black coating is perfect with no markings. Includes spare bearings. This is going to be the rail for the X-axis of an Ender 3 V2.

One rail is so tight it barley moves and the other is so loose that it does not stay straight has a bunch of wobble in it

Didnt expect much from these and I was right. carriages need to be cleaned and oiled/lubed to get decent movement. getting some rust spots on the rail after about a month of use. not the best but they get the job done.

I have used 3 different brands of linear rails, and short story is IMHO you can find better. Spent a lot of time cleaning and lubricating, and then cleaned again and tried a few different lubes. OK is as good as these get.

I know they are not the best you can buy but for the price all I had to do was wash them and the bearing blocks in IPA. and then re-lubed them in WD40 lithiumThey work absolutely GREAT
