All the cleats have been added to the foremast.
Yes, there really are more cleats on the foremast than the mainmast. They handle the brails, foresail tack, and something else that I don’t remember at the moment. The picture below is from my visit to the Sultana in 2018.
The mast hoops were very simple to design.
A nice side effect of the 3D printing process is that the filament layers ended up creating a kind of simulated wood grain on the mast hoop pieces. Adding wood stain onto the beige plastic makes them look convincingly wooden.
