Often it helps me to see how I've broken down parts by colouring them so I can see if something might be too unwieldy to cast. There's a physical limitation I have to consider size of my pressure pot which I use for both degassing the silicone and pressure casting the parts.
I had it before where a mould was just too big to get the lid on lucky it was just case of trimming down the top of the mould box (usually you make it 2/3 model 1/3 expansion room for degassing)
As you can see there's lot of parts. The more parts the more the silicone cost go up since you need a few CM of silicone around the part to give the mould strength the more it costs to make so the dome turrets for example are up for debate where they rotate or not. I think there's about 40ish part so far lots of long flat pieces with honestly are an unknown casting wise for me. So there be a bit of research on the best way to break this down and cast it.
