Hi

I've been trying to figure out this challenge for a while but I've gotten no closer to a solution.

The simplest example of what I'm trying to achieve is to imagine 3D printing a jigsaw puzzle. In order for the pieces to have more spacing/margin I would like to sand off a small amount of the outside of the puzzle pieces. Does anyone have an advice on a program or technique that could do this?


A little background info. I'm actually trying to 3D print a map of a country with some spacing between the main areas/counties. My first thought was to just resize each piece individually but of course this wouldn't help at all. My second idea was to look into techniques for hollowing 3D models before printing. That would potentially give an idea on how to solve this. Sadly, most of those are either using a one button hollow functionality or are simply using basic objects (sphere, cylinder) to hollow the object. So I'm still no closer to solving this.

Thanks for any idea and tips on how to get closer to what I want to achieve here...
