Lattice Structure design fused

here is another one, but fused. and this i love the interior design and it feels like a solid mass, but lighter. it's a weight differences and it's amazing. the same problem on top where there is bonding issue. but this is for fun and maybe some few test. but this was for fun and i will try another one, but there is problems, but it will be fine.
hope you enjoy, the same setting is the previous lattice in my profile. and enjoy.
