Your party of adventurers stands on the docks, the scent of salt and sea filling the air. Before them isn’t just a drawing on a map, but a fully realized, multi-level galleon, ready for exploration, combat, and untold stories. This isn’t a pre-made model; it’s a custom-built OpenLOCK ship, and it’s about to take your tabletop game to a whole new level.
For tabletop gamers and 3D printing hobbyists, the OpenLOCK system offers a universe of creative possibilities. In this guide, we’ll explore what an OpenLOCK ship is, how you can build your own, and why this modular system has become a game-changer for creating immersive RPG experiences.
What Exactly is the OpenLOCK System?
Before we set sail, let’s understand the mechanics. The OpenLOCK system is an open-source standard for creating modular, interlocking terrain pieces for tabletop games like Dungeons & Dragons and Pathfinder. Developed by Printable Scenery, it uses small, standardized clips to connect walls, floors, and other components.
Think of it like LEGO bricks for your game world. You can 3D print individual tiles—a floor piece, a wall section, a doorway—and then clip them together to build dungeons, castles, taverns, and, of course, ships. The system’s strength lies in its modularity. You can easily assemble, disassemble, and reconfigure your creations for endless replayability.
The “open” in OpenLOCK is key. Because the standards are public, a massive community of creators designs and shares compatible files. This means you have access to thousands of pieces from various designers, allowing you to mix and match to build the perfect environment for your story.
From Dungeon Tiles to High Seas: The Rise of the OpenLOCK Ship
The OpenLOCK system began with a focus on classic dungeon crawls. The ability to build custom layouts room by room was revolutionary for Dungeon Masters (DMs) who wanted to move beyond flat battle maps. Players could physically interact with the environment, opening doors and moving through corridors in a tangible way.
As the 3D printing community grew, so did the ambition of its designers. The natural evolution was to take these modular principles and apply them to more complex structures. Ships were a perfect fit. An OpenLOCK ship isn’t just a static model; it’s a dynamic, playable map with multiple decks, cabins, and features.
These ships can be built level by level. You can start a battle on the main deck, then remove it to reveal the crew quarters or cargo hold below. This “fog of war” effect adds suspense and excitement to your game. Players don’t see what’s on the lower decks until their characters physically go there.
Building Your First OpenLOCK Ship: A Hobbyist’s Guide
Ready to add a vessel to your fleet? Getting started with an OpenLOCK ship is an incredibly rewarding project that combines the fun of 3D printing with the creativity of tabletop gaming. Here’s how you can begin.
Step 1: Find Your Perfect Ship Blueprint (STL Files)
Your first step is to acquire the digital files, known as STL files, needed for printing. You can find these on various platforms where 3D designers sell or share their work. Marketplaces like MyMiniFactory are a great starting point, as Printable Scenery and many other creators have extensive storefronts there.
Look for ship designs that explicitly state they are “OpenLOCK compatible.” Popular designs often include everything from small sloops and fishing boats to massive, multi-masted warships and fantastical spelljammers. Read reviews and look at photos of finished prints to find a design that inspires you.
Step 2: Fire Up the 3D Printer
Once you have your files, it’s time to start printing. Building a full ship is a marathon, not a sprint. You’ll be printing dozens, if not hundreds, of individual pieces, including:
- Hull Sections: The curved pieces that form the body of the ship.
- Deck Tiles: The flooring for each level.
- Masts and Spars: The tall poles that hold the sails.
- Details and Scatter: Cannons, railings, steering wheels, anchors, and cargo.
- OpenLOCK Clips: The small but vital connectors that hold everything together. Print plenty of these!
For most terrain pieces, PLA (Polylactic Acid) is the perfect filament. It’s easy to print with, affordable, and sturdy enough for game nights. A layer height of 0.2mm is a good balance between speed and detail for larger parts like hull and deck pieces. For smaller, more detailed items, you might consider a 0.12mm layer height.
Step 3: Assembly and Customization
With all your pieces printed, the real fun begins. Lay out your components and start clipping them together. It’s best to assemble one deck at a time, starting with the keel and working your way up. Follow the designer’s instructions if they provided an assembly guide.
This is also your chance to get creative. Don’t be afraid to “kitbash” or modify the design. Maybe you want to add an extra cabin or place cannons in a different layout. The modular nature of the OpenLOCK system makes customization easy.
Step 4: Painting and Finishing Touches
A coat of paint will bring your ship to life. You don’t need to be a master artist to get great results. Start with a base coat of primer, which helps the paint adhere to the plastic.
- Base Coats: Apply your main colors. Use various shades of brown for wood, grey for stone elements, and metallic paints for cannons and anchors.
- Washes: Apply a dark wash (thinned-down black or brown paint) over the entire model. The wash will settle into the cracks and crevices, adding depth and shadow.
- Dry Brushing: Take a lighter color, get a small amount on your brush, and wipe most of it off on a paper towel. Then, lightly brush over the raised surfaces. This technique highlights the details and textures, like wood grain.
Finally, add rigging using thread or elastic cord to complete the look. Your OpenLOCK ship is now ready for its maiden voyage!
Why Every Gaming Table Needs an OpenLOCK Ship
An OpenLOCK ship is more than just an impressive centerpiece. It fundamentally enhances the gameplay experience.
- Unmatched Immersion: Placing a physical, 3D ship on the table instantly draws players into the world. It makes the adventure feel more real and consequential.
- Dynamic Combat: Naval combat becomes far more tactical. Characters can climb rigging, swing on ropes, take cover behind masts, and blast enemies with cannons. The multi-level design allows for complex, three-dimensional encounters.
- Endless Reusability: Once the adventure is over, you can disassemble your ship and store it easily. Or, you can reconfigure it into a different vessel for your next campaign. That massive galleon can be rebuilt as a pirate frigate or a merchant vessel.
- A Rewarding Hobby: The process of printing, building, and painting your own ship is a deeply satisfying hobby in its own right. The final product is a testament to your creativity and effort.
Embark on Your Next Great Adventure
The OpenLOCK system has transformed how we build and interact with our tabletop worlds. By extending its modular principles to the high seas, designers have given DMs and players the tools to create epic naval sagas.
Building your first OpenLOCK ship is a gateway to a new dimension of tabletop gaming. It’s a project that combines technology, art, and storytelling into one incredible package. So, gather your files, warm up your printer, and prepare to set sail. Your players will thank you for it.
