Wooden eyeglasses

thingiverse

Got the idea when returning from a visit to Fab Lab Berlin in July 2014: An intern had cut a bendable cover for his report, probably thing 12707. There was lots of talk about digitally manufactured glasses. For the future Optimize pattern for bending. Currently it's guesswork: Based on thing 12707, I simply drew something that I thought could work, and it does. Make eyeglasses foldable flat, fixable with cords. At the moment, the temples collide, preventing bending both by 180°. Parameterize design for different faces. Experiment with different cords. Instructions Choose one of the two provided designs. The pictured frame was cut in 3 mm birch plywood. The glasses themselves were cut in 3 mm acrylics with a 0.3 mm outside offset to compensate for kerf width. They fit snugly into the frame — no gluing necessary. For use as sun shades, I would have preferred a material with a stronger tint. However, when having the opportunity to cut, I didn't have any at hand. To make the nose bridge more comfortable, consider filing it round and applying some Plasti Dip. Cords are 3 mm in diameter, made of acrylics. I heated the ends with a lighter. A material that doesn't extend much is preferred.
