New - Where to get OX side parts?

Hello,

What a great site! I am thinking about putting together a build of one of the machines, the OX has caught my eye.

One question, the OX requires CNC milled parts to put it together. How do others do that? Is there an online site that I can order the specific pieces that are milled? Or do people go to local makerspaces?

I realize the obvious answer is build something to build pieces to build the next...But that seems to extend time and budget significantly.

THanks,
Casey
