This little STONE/ROCK PEDESTRIAN BRIDGE is scalable within reason. Print it black or dark grey and then paint multi-colored rocks. I exclusively print with PLA and have found that ordinary clear lacquer thinner (Nail polish remover) is a wonderful glue. Make a small test for yourself of two pieces of printed scrap PLA and give it a try. Let sit for 20 seconds and then try to break it apart. It leaves no residue and is applied with a small brush. I've been using lacquer thinner as a glue on stryene and PLA for years. No sloppy or messy glue to show when finished.
