Our first assignment, Physical Digits putting our laser cutting skills to the test. An exercise in perfect joints, the bolt and nut must be 'friction fit', held in place by perfectly cut acrylic. With a tightly packed dFab schedule and 50 some eager archies, we began developing a spatial understanding of the nut/bolt relationship. Below I've included a pic of my sketchbook and my skirt. I worked through various 'blox' designs in the sketch phase, noting measurements and critical equations as I went.
Departing from analogue methods, I began working out the geometries necessary for my design (thank you, Descriptive and Matt Porter). Using these basic mathematical principles and the precise measurements of the Dial Caliper, I was confident to move into the prototype phase.

This blox was really starting to come together. Next step (more than a week later) off to the laser cutter! Hindsight 20/20: dFab(ulous) as soon as possible. The mad dash and my sleepiness cost me in this assignment.

I'm proud of my little blurry labels. Testing for the perfect fit required understanding how the cut sheet translated in the cutting process. The offset curve of a cut is usually .0025 based on Legend 36EXT's kurf (width of the laser cut). I actually lost my rusty nut and bolt, but since I'd left myself with many options for fit I had no trouble substituting in another pair.From lifting the hood of the laser to photographing my finished piece is a blur... I've displayed my funky creations below.
