Experimenting with different types of structures this week, this is the latest:
Assembling the last pieces was difficult. If I did it again I’d loosen up on my tolerances to make it easier to build. Total of 36 pieces of 1/8” Baltic birch. No glue. Very sturdy, could easily be adapted into a light shade. This sort of structure could scale very well, could probably triple in diameter without going to 1/4”, after that weight might be an issue. Slot geometry is tricky to work out, but worked on the first try.
