Today, Kaho and I took another class taught by Hung – an
introduction to the CNC milling machine. The machine can apparently cut
on three axes. We got to mill a little gear pattern into squares of
aluminum with a round bit.

After learning about the milling machine, I moved on to my other
project, the salt and pepper shakers made on the 3D printer. I made a
slight modification to the lid to my salt shaker, and asked Hung to
print one of all three parts. Apparently, they’re now printed and
waiting for me at TechShop.
