Arm 1 sparks joy. Arm 9 does not.

Instruction breakdown by chamber: 13i metal + 15i anime + 23i assembly

Could save maybe up to 3i in the anime chamber, and like 7i in assembly. There's surely a much more efficient way to build the product in 1/6P that I'm missing.

I would be shocked if sub-40i was achieved, but you never know with this community.
