I had intended to build the X301 mostly out of parts I had laying arount from the last time I was really into 3D printing. Unfortunately, that was so long ago that I just had a bunch of 12V parts and RAMPS boards. Additionally, the world has changed quite a bit since the X301 was first created in the beginning of 2020. With that in mind, you can check out my Bill of Materials to see what I ended up going with, where I got them, and an idea of how much I ended up paying for them.
