I thought I would share some food for thought and hope that others would add to this as well. Not necessarily Glowforge copyable in themselves but inspirational to concepts that could be used elsewhere.
For starters, I keep looking at these two Medieval architectural designs and thinking of how I could use them to create tables that would escape the 19" size limitations to make big things of parts the Glowforge can make.
This as example sort of begs to be made into a table. and this (below) points the way with ideas as well.
