This is one of several balance objects I am working on, should be laser cutting it this afternoon at Bower Ashton Fabrication with the ever-helpful Zarya.
This will be in 3mm plywood, I won’t be able to assemble it today as the stud axels have not arrived yet. I could use something else I suppose – possibly a job for the 3D printer. Or I might just use a small plastic stud of the sort found in car part shops. The assembled object needs additional balance which is supplied by a party balloon with a little water.
