Makergear M2: Fundamental Test Object

Test 3D prints. Not quite art pieces but print a bucket full of them, dump them on a table and take great care making a photograph of them, and they appear as something more than just test 3D models.

By the way, I initially though the slanted position of the internal cube against the outer frame on the first picture was intentional. You don’t want that in a production 3D model but for calibration this approach works: as soon as you add long straight lines at acute angles, inaccuracies of stepper movement, non-plumb axis and other issues start popping up.
