+Deciding which face to print is somewhat of a tossup for these two pieces, as far as strength goes. Pictured is the print orientation used for testing and the test printer has been going strong for 6 months now with no issues.

+A great help in mounting the rails is an [MGN12 alignment tool](https://www.thingiverse.com/thing:2368837). There are dozens of other options on Thingiverse and Printables. You'll want to print this tool before the next step.

+1. Loosen the X and Y belts then slide the Y belts out of the wheel plates. You won't be able to reuse these belts so you can toss them.
+1. Remove the v-slot wheel screws and wheels on the left wheel plate
+1. Remove the two screws on the underside of the plate which attach it to the X gantry and save one of these screws for later
+1. The plate can now be removed from the gantry
+1. Using M3x8 screws and T-nuts, attach an MGN12 rail to the frame (this is where the alignment tool comes in handy)
+1. Attach your new left linear mount (the smaller of the two) to the linear bearing block (the slidey thing) using M3x8 screws
+1. Press the X gantry into the 20mm cutout in the mount then use one of the M5 screws from step 3 to secure mount to the X gantry from the underside

+> The purpose of this stage is to add a linear rail on the X axis. We'll basically be trading the weight from the original steel printhead carriage and its wheels for an MGN9 rail of similar weight. Thus, the benefits of this stage aren't as much weight removal as the ability to use a modern printhead such as the Ratrig EVA or the Vz Printhead, plus complete liberation from those frustrating v-slot wheels.

-[^1]: Because stage 3 adds a linear rail to the X axis, the weight of the new rail does negate the weight saved by dropping the v-slot printhead carriage. This stage isn't as much about dropping weight as the other two stages were. The benefits of this stage are mainly more print consistency on the X axis, access to the awesome Ratrig and Vz printheads, and complete liberation from those v-slot wheels.
