Y AXIS DUAL-RAIL MOD VERSION 2 (no drilling required)

thingiverse

****** PLEASE BE INFORMED THAT THIS MOD WILL ONLY WORK WITH EARLY VERSIONS OF ENDER 3 WHICH UTILIZES PLATE BRACKETS WITH A RHOMBUS V-WHEEL ARRANGEMENT INSTEAD OF SQUARED****** This is my second design for the Ender 3's Y-axis dual linear rail conversion. The major difference between this version and my first one is that it utilizes the existing plate bracket that holds the heat bed and v-wheels. As the title indicates, this version doesn't require drilling new holes in your plate bracket. (1st version https://www.thingiverse.com/thing:3299040 ) Is this necessary? No, it is not. Sticking with the stock v wheels or doing the single rail will do just fine. The only benefit you'll get from doing this if it's done correctly is that you'll lose very minimal z height compared to the single rail mod (around 5mm). A guaranteed solid base compared to the stock and your driving force will remain at the center of the bed unlike with the single rail, it will be shifted a little bit towards the right side. Additional parts required are: 2x 300mm MGN 12H M3 x 12mm x4 for mounting the printed bracket to the Y plate M3 x 10mm x 10 + T-nuts (for mounting the rails to the Y frame, I only used 5 on each side) M3 x 12mm x4 (for mounting the new Y bracket mod to the rail block) M4 x 16mm x2 + T-nuts (for mounting the Y switch bracket on the Y aluminum frame) https://www.youtube.com/watch?v=kJIqcmiXYpg
