Hey guys, I'm new here. I was planning on making some Settlers of Catan 3D pieces, and I was wondering how well they would snap together...For instance, the pieces will be able to connect, but I dont want effort required (like lego). I want it to be so I just drop it in and it fits, know what I mean? I'm also having a tough time choosing the material, because the only one that's multicoloured is that rough sandstone one and I'm not sure how durable that would be for game pieces. Any advice would be awesome. Thanks!
