If you've ever been around lathes and mills, you'll be able to appreciate most of it. It's simple and also brilliant, filled with "holy shit I can't believe you can do that" things...
Well - I too can create "shit I cannot believe you can do it" stuff, like this one: its 33 mm x 120 x 4 mm stiffening plane, it prints in less than 20 minutes and weighs less than 3 grams. The lead-in is the only time the nozzle moves without also printing, the whole model is one long line.
