For a single top mounted MGN linear rail.
This set of files will allow you to convert your Ender 3 with a bottom 2040 aluminum extrusion to MGN style linear rails this should in theory work with MGN9 but I used MGN12H.
Story:
Here's the rundown of how I came up with this: I had an extra MGN12H laying around after attempting to convert my V3 SE to a linear X axis and realized it's too big. I just got a couple ender 3's with a 2040 extrusion. Kind of works out because you can use a single rail. but now you have to mount the rail to the side or re-route the belt and the first option is lame so I chose the latter. simple enough and a lot of printers I see online are practically entirely 3D printed and I have some ASA so frick it why not. And this is the result!
Please forgive the poor print quality in my pictures I was printing ASA at 160mm/s and my input shaping isn't perfectly tuned.
Feel free to improve my design, I want to see what you come up with!
