A challenging 3D puzzle of the Gale Crater on Mars, made with the help of NASA's 3D model library. A frame is also included. I recommend printing my test puzzle first to make sure your printer is accurate enough (.15mm should be a tight fit, .3mm should fit nicely)

The puzzle is 150mm x 150mm when complete, but you can print a few pieces at a time, so build volume shouldn't be an issue.
