Paint 3D printed models: Here’s how

I recently acquired a 3D printed door for my Commodore 1084 monitor. It was missing its original. Of course, it came in white. I can live without an imperfect match, but I want something closer than white. But can you paint 3D printed objects? Yes you can. Here’s how to paint 3D printed models.

Gaslight Square, St. Louis

Gaslight Square, St. Louis

Gaslight Square was a popular arts and entertainment district in the St. Louis Central West End neighborhood whose heyday ran from the mid 1950s to the mid 1960s. It was a three-block area near the intersection of Olive and Boyle, a mile or so north of what’s now the Cortex District. Today, suburban-style housing stands where the clubs and shops once stood.
