I’m also a model-maker and love scratch-building pieces for my dioramas. I’ve been bringing my skills as a modeler to my book arts and it’s been a fun crossover. Here I built a dumpster out of polystyrene and spare parts. Those bumpers on the front panel are helicopter blades. It was a fun because the end product needed to look used and abused, so any artifacts and foibles from the build process would just add to the sculpt.
Originally, I wanted the lids to pivot in small hinges, but it became pretty obvious that was going to be difficult to mold, so I switched to lids that were simply removable.
