**Linear Rail.** ### Y Linear Rail Mod V2. ---------------------------------------- [Bobblejot Website](http://bobblejot.com) [Bobblejot GitHub](https://github.com/Bobblejot/) [Bobblejot Twitter](https://twitter.com/bobblejot) [Bobblejot Patreon](https://www.patreon.com/join/bobblejot?) ---------------------------------------- **Update 070419** Added **Y_Idler_NI.stl** & **Y_Motor_Mount_Back_NI.stl**, the only change being the removal of holes for brass inserts. Not everyone likes them or wants to use them, so this way you can just thread into the plastic body. Added **Y_Limit_Switch_Bracket.stl** & **Y_Limit_Switch_Bracket_Offset.stl** to mount the original Ender 3 Endstop to the right-hand side of 2040 extrusion (closest to the z motor), it should position the endstop to activate off the edge of the bed plate. I have uploaded two versions because I haven't been able to test the bracket, and one of them should work to get the endstop in the correct position. ---------------------------------------- This is the second version of a linear rail mod for the Creality Ender 3 and the one I am using now. This mod was done to improve the belt path alignment and create a sturdier platform. With this mod, I have provided a drill guide for either the standard or wide version of the mgn12 carriages. In my pictures, you will see a smooth idler; it was only used because I ran out of toothed idlers and had to order more and was too impatient to wait for them to arrive before doing the mod. When the belt wraps around the platform tabs, I go over then wrap under so the teeth of the belt are gripping each other, then I tie-wrap them together. When installing, I fix the motor mount solidly and leave the idler slightly loose and pushed as far back as possible. I just bought these because I needed spares.
