This is a simple but working mod to replace X Axis V slot for a linear rail, you can use same V-slot screws but will need 4 x M4 nut. Print the right and left parts with strong PETG or ABS as minimun 30% infill. I use a Mellow NF-BMG-WIND so need the body part too, if you use the default hotend you don't need the body part. Unmount hotend removing the wheels, you can directly mount again without wheels on the new roller support (if you have the original one), then unmount X Axis V slot, you will need to remove 4 screws from metal backside. For mounting the linear rail you need: 350 mm MGN 12H linear rail 4x M4 from V-Slot 4x M4 hex nuts 5x M3 hex nuts 5x M3x12 screw Once you have printed parts: 1) Mount 2 x M4 screws on right front part and 2 x M3 Hex nuts at the back, use a M3x18 screw to fix the nuts in the internal hex hole, then do the same for left part, this one has one more M3 Hex nut. 2) Place and fix parts to X Axis support 3) Place and fix Linear rail to installed parts, no matter orientation, ¡¡look where are the 4.A) If you are using the default hotend, you can fix the metal carriage using a longer M3 screw on the left hotend hotel so will pass through the carriage and fix on the upper left hole from roller, then use 2x M3x5 screws to fix from bottom linear hole at carriage to bottom holes at roller. 4.B) If you are using another extruder the body part has two holes that fits with my extruder Mellow NF-BMG-WIND, hope if you use another you can find the way ... THAT's ALL!!
