Very cool article! Thanks for sharing. Is numpy just global in Python now? I see it everywhere, and I eventually sound it out. Yet I never fail to have a few moments where I go, “Wait, what is ‘np’? Oh, yeah… Numpy.” And I always feel like just listing it as an import in the snippet would’ve solved it.

Just a “standard” convention. I’ve been doing a bunch of analysis work lately and almost all of the scripts start with something like:

    import numpy as np
    import pandas as pd
    import seaborn as sns 
    import sympy as sp

I think you could if you had a small bench top cnc or laser cutter.

You’d have to split up the DXF into pieces that fit on your bed, but you’d be able to make a template by joining the parts together.

Then rough cut your workpiece to the template, followed by a flush bit router.
