3D Prints by Gary creates modular 3D printable terrain for tabletop games, RPGs, skirmish games, and miniature gaming. The goal is simple: make terrain that looks great on the table, prints reliably, and works together as part of a growing system.
Rather than designing every STL as an isolated model, our terrain is developed around shared dimensions, connection methods, and compatibility standards. That means a floor tile created today can be designed with future walls, buildings, caves, roads, elevation pieces, and accessories in mind.
The result is a terrain collection built to expand with you.
Terrain Designed as a System
There are countless excellent individual STL models available for 3D printing. What interested us more was building something larger: a modular terrain system that could grow over time without turning into a collection of unrelated parts.
3D Prints by Gary terrain is designed around repeatable mechanical standards. Compatible pieces share common footprints, connector locations, elevation interfaces, and proportions so that different terrain families can work together.
A dungeon does not have to remain just a dungeon. A layout can expand into a fortress, rise onto elevated ground, transition into wilderness, connect to buildings, or eventually incorporate entirely new terrain collections.
The idea is to give you building blocks rather than predetermined maps.
Made for the Tabletop
Our terrain is designed primarily for 28mm to 32mm miniature gaming and uses practical inch-based dimensions that work naturally with many tabletop RPGs, dungeon crawlers, and miniature games.
The system includes more than decorative scenery. Depending on the collection, you may find:
- modular floors and terrain tiles
- dungeon and cave environments
- walls, doors, pillars, and architectural components
- towers, ramparts, and fortifications
- wilderness and natural terrain
- roads, paths, and environmental features
- elevation pieces and risers
- removable scenery and accessories
- connectors and supporting components
The emphasis is always on giving you pieces that can be rearranged into many different encounters rather than requiring a specific layout.
Designed With 3D Printing in Mind
A model can look excellent on a computer screen and still be frustrating to print.
That is why 3D Prints by Gary is developed with real FDM 3D printing in mind. Terrain is designed around practical considerations such as orientation, strength, repeatability, fit, and the realities of printing larger collections of pieces.
Where applicable, mechanical parts such as connectors and sockets are designed to remain consistent across compatible terrain sets.
Production models are also versioned so improvements can be tracked rather than silently replacing one file with another. The goal is to build a dependable library that can continue developing without losing track of compatibility.
Print. Connect. Rebuild.
One of the biggest advantages of printable terrain is that you are not limited to a single battlefield.
Print the pieces you need. Build a dungeon for one session. Rearrange the same collection for the next game. Add another terrain set later and create something larger.
Modular pieces make it possible to continually change the table without continually replacing your terrain.
That philosophy is at the center of 3D Prints by Gary:
Print it once. Use it many ways. Keep expanding.
Why “3D Prints by Gary”?
Because this is meant to feel like a workshop, not a giant anonymous STL marketplace.
The terrain comes from an ongoing design process of building, printing, testing, changing things that do not work as well as they should, and developing new pieces that fit into the larger collection.
Some releases begin with a simple question: What piece would make this system more useful?
Others come from an idea for a new environment, structure, connection method, or way to add verticality to the tabletop.
Either way, the goal is the same: create terrain that we would actually want to print and use ourselves.
A Growing Terrain Library
3D Prints by Gary is intended to keep growing.
New terrain families, expansions, alternate pieces, structures, accessories, and improvements will continue to be added as the system develops. Some releases will dramatically expand what you can build, while others may simply solve a small problem or add another useful option to an existing collection.
Because the terrain is being developed around shared standards, those additions can become part of a larger ecosystem rather than starting over every time a new set is released.
Build Your Next Table
Whether you are printing your first dungeon or building an entire modular terrain collection, we want the process to be enjoyable from the printer to the gaming table.
Browse the terrain, choose the pieces that fit your games, and build the world you want to play in.
