What parts do I need to print?

I have an LDO Rev D 250 Trident kit and a Siboor CNC parts kit. I'm a bit confused about which parts I still need to print and which parts I can skip printing because they’re replaced by the metal Siboor parts.

Is there any list or guide that could help me choose which parts I need to print? I don’t mind printing a couple of extra parts by accident, but I don’t want to print the entire standard parts list and then not use several of them. I’m also trying to avoid printing one or two parts at a time as I build, and would rather print in larger batches.
