We live in an age of wonders. Well, okay, you could say that of any point in history, but I have to remind my kids that things like my oldest son’s 3-D pen simply did not exist when I was a kid. Somewhat haphazardly, he can create three-dimensional objects on an empty table where that object did not exist before. He didn’t have to prototype it in a CAD program and send it off for someone to do a test shot. He just…drew something in 3-D. I was born in the 1970s, and was present for the transition from foot-tall G.I. Joe figures to Star Wars figures that fit in my shirt pockets. I had Spirograph. My kids have pens that draw physical constructs in mid-air. My mind boggles. I want to play in that world. I can’t afford a 3-D printer. But maybe I can dip my toes in the water by obtaining something 3-D printed. Like these.
