OrbitStudio

Print any place on the Moon or Mars as a snap-together puzzle or ornament

OrbitStudio turns real NASA elevation data into printable terrain. Spin the globe, frame a crater, a landing site or a volcano, and the generator builds the surface at the size you choose. The Moon is covered in full, nearside, farside and the south pole, and Mars uses MOLA altimetry at up to 463 metres per pixel.

We built OrbitStudio ourselves. It is listed with the same pros and cons as every other tool.
