I am curious about this. Would you please discuss it further? I like the idea of mental models that can be used in useful ways, or programmed in some way. The method of loci comes to mind. I have a mental representation of a semi permeable membrane that helps me intuit about which way osmotic pressure will push fluid in a given system. Some other useful mental models: SCP cognitohazard (to think of/perceive a cognitohazard is hazardous), mental models of triangles are useful for estimating load angles when rigging heavy machinery, tenth thicknesses are a useful model to determine how much radiation shielding is needed for a given radioactive source of x rem strength. Mental models can be very powerful tools, and the best part is that they have a very low cost of replication, being information. They exhibit the property of medium independence, being able to be replicated as a series of interactions that serve as the holding media of the information. Your brain holding the mental model of the item is an example. I have mostly pondered the mental models relating to straight lines and closed regular geometric forms. Help me ponder the orb.
