Print a piece of the Moon, Mars — or the night sky you remember.

Yes. Generating a model is free in both tools, and so is StellarMesh's STL. Downloading a Moon or Mars model, or a StellarMesh multicolor 3MF, uses one credit from a campaign pass.

Passes start at $10, one time. There is no subscription. The tiers and what each one includes are listed on the MakerWorld campaign page.

Every model comes as an STL and as a multicolor 3MF with the colours already assigned, ready for Bambu Studio and OrcaSlicer. Both tools make models that print on any FDM printer, with no supports. Always check geometry, wall thickness and supports in your own slicer before printing — printers, profiles and materials vary.

The Moon comes from NASA's LRO LOLA elevation data and Mars from NASA's MGS MOLA. StellarMesh's stars come from the Yale Bright Star Catalogue, down to magnitude 6, and its constellation figures from the IAU and Sky & Telescope. The planets and the Moon on a star chart are computed for the moment you pick.

OrbitStudio turns real orbital elevation data into 3D-printable models. Pick a region of the Moon or of Mars, and it generates a jigsaw puzzle or solid ornament — downloadable as an STL file and a pre-configured, Bambu Studio-ready 3MF file.

StellarMesh is OrbitStudio's sister tool for the night sky, from the same maker. Pick any place on Earth and any date and time, and it builds the sky over that spot as a star chart plate: the stars down to magnitude 6, all 88 constellations, and the planets and the Moon where they stood. The chart is built in your browser. The STL is free and needs no account. The multicolor 3MF uses one credit from a pass, which covers that chart's desk stand too, and downloading the same chart again costs nothing more.

Not to try it. Anyone can generate a terrain and preview it in 3D without signing up — guest models are held for 48 hours, then cleared. A free account needs no validation code and lets you slice that terrain into a puzzle, add text, name it and keep it in a library of three. StellarMesh needs no account at all to make a chart and download its STL. Downloading a terrain model or a StellarMesh 3MF is the part that needs credits from a pass: backers receive their access code between 10 and 24 October.

For Moon and Mars terrain, yes — a fair-use limit, not a paywall. Without an account it's 10 generations per rolling 24 hours. A free account gets 15 per rolling 24 hours and 300 per rolling 365 days; an account with credits on it gets 100 and 5,000 over the same two windows. All of those sit far above normal use — they keep the service fast for everyone and stop automated scraping, not makers. Need more? Email us and we'll normally raise it. A StellarMesh chart you only make in your browser does not count toward it; one you save to your library counts the same as a generation.

Every tier lets you print for yourself and give prints as gifts. Selling physical prints requires the Merchant tier — on that tier you can sell prints and use photos or video of them commercially, though the digital files themselves can never be resold or redistributed on any tier.

Printed puzzles are not toys and are not suitable for children under 3 — small interlocking pieces are a choking hazard. Keep printed pieces away from small children and pets, and supervise older children.

Yes. The Moon comes from NASA's Lunar Reconnaissance Orbiter — LOLA elevation data and WAC imagery. Mars comes from NASA's Mars Global Surveyor — MOLA altimetry at up to 463 metres per pixel, with Viking MDIM 2.1 imagery. At the default 1x the heights are true to scale; many regions look flat that way, so a terrain exaggeration setting lets you raise them. Models are decorative representations, not survey-grade.

Credits and Passes aren't refundable once a code is redeemed, and they have no cash value. That's because access begins immediately when you redeem — this doesn't affect your statutory rights if something we deliver is faulty.

Yes, any time, from your account settings. We remove your account data within 30 days, except where we're required to keep records by law.
