In short: I have a heavy, detailed 3D model good for fabrication, but I only care about its looks. Call me superficial if you must. :-)
See this model of a vintage 1963 USPS Street Collection Mailbox:

The reduced model will be used for a static scene and animation and the expert in charge told me to get him something lighter.
In the abstract, I wish I somehow get rid of all the metal and leave the visible, shiny paint alone.
