SifVerT - Difficulty Tuner
There's an option to enable "Machine Parts" if you disable the crafting table, which is kind, but it also adds several milestones to research to unlock the assembler/manufacturer/etc that can be built with machine parts.
However, with machine parts disabled, the milestones to unlock these machines still appear. I'm not sure if this is intended behavior or not.
