Tonight, I was on assignment for Brandon and the Makery Mendel again, this time drilling some really really tiny holes. These acorn nuts will be used as print heads to extrude the molten plastic on the almost-done Makery Mendel 3D printer. I started the process by holding the piece of allthread (Which has a shallow [...]

His drawings aren’t [...]
