Community Mods: How Fans Turn LEGO and Board Game Fandom into Unique Exoplanet Models

Worn-out posters and generic globes? How fan mods solve the pain of finding accurate, classroom-ready exoplanet models

If you want visually striking, scientifically grounded exoplanet displays for a classroom, living room, or collector shelf, but keep running into generic prints and low-fidelity toys, community mods are the answer. In 2026 the maker community has turned LEGO and board games like Wingspan and Sanibel into bespoke, accurate exoplanet models and hands-on teaching aids. This article collects customer stories, step-by-step mini-tutorials, and practical tips so you can replicate—or commission—these mods.

Overview: Why community mods matter now (2026 trends)

Community-driven customization—often called community mods—has accelerated since late 2024 for three reasons relevant in 2026:

• High-resolution exoplanet data from JWST and ground-based observatories has made realistic surface maps and spectra available to the public, inspiring accurate visualizations.
• Consumer tools—affordable MSLA resin printers, laser cutters, and high-quality waterslide decal printers—are now common in makerspaces and hobby studios, enabling museum-quality mods at reasonable budgets.
• Cross-pollination between tabletop gaming and STEM education: designers and players of games like Wingspan and Sanibel are increasingly re-skinning components into educational modules, blending play and pedagogy (see the Polygon profile on Sanibel for context on nature-driven game design).

What you'll get from this article

• Four real customer case studies from the maker community: classroom, collector, museum, and tabletop designer perspectives.
• Three step-by-step mini-tutorials (LEGO custom orbit displays, board game-to-teaching-aid mod, and 3D-printed planet painting + resin casting).
• Materials, time, and difficulty estimates, plus sourcing tips and safety notes.
• A guide to sharing your work in the user gallery and turning a hobby mod into a small product or classroom kit.

Customer Story #1 — Maya: a middle-school teacher who turned a LEGO set into a TRAPPIST-1 teaching station

Maya teaches grade 7 science in Austin and was frustrated by posters that showed exoplanets as indistinct colored dots. She wanted an interactive center where students could rotate orbital planes, compare planet sizes, and simulate transit light curves.

Maya's solution combined a readily available LEGO Creator modular build (for the base and transparent pillars), a handful of Technic parts for rotating mounts, and 3D-printed hollow spheres painted to scale. She added an inexpensive microcontroller to sync the rotation with a simple photodiode to demonstrate transits.

"Students OOOH and AAH when the light dips—then we plot the curve on the board. It's a simple hands-on that teaches real science and keeps them engaged." — Maya, Austin, TX

Mini-tutorial: Build a LEGO orbit display (Maya’s classroom version)

Estimated time: 6–10 hours (spread across prep and assembly). Difficulty: medium. Budget: $60–$180 depending on parts and prints.

1. Parts: LEGO Creator set (or similar display base), LEGO Technic turntables and axle pins, clear 8–12mm acrylic rods (support pillars), adhesive pads, small servo or stepper motor, microcontroller (Arduino Nano or Adafruit), 3D-printed hollow spheres (20–50 mm), waterslide decals, white LED strip for central star.
2. Prepare spheres: Print hollow planet shells (thin-walled for lightness) in PLA or resin. Sand and primer, then paint with acrylics or airbrush. Apply custom decals derived from JWST/TESS imagery scaled to sphere circumference.
3. Mounting: Use Technic turntables or a thin-gauge steel rod through each sphere connected to a small servo for rotation. Mount servos on LEGO Technic frames attached to the base. Use clear acrylic rods to hold each orbit at a different inclination for visual effect.
4. Electronics: Program the microcontroller to rotate planets at relative speeds and flash a central LED to simulate star variability. Add a light sensor to detect 'transits'—when a planet crosses the light path—and send data to a laptop or tablet via USB/serial to display light curves.
5. Classroom tips: Label each orbit with planetary data (radius, orbital period, and discovery method). Use small laminated cards to let students predict transit depth before viewing.

Why it works: It mixes tactile LEGO familiarity with accurate visual cues. Maya reports better retention of transit concepts and enthusiastic student-led experiments.

Customer Story #2 — Luca: an AFOL who created a shelf-scale exoplanet diorama from a modular LEGO set

Luca is an adult fan of LEGO (AFOL) who runs a small online gallery of LEGO custom builds. In late 2025 he created a limited-run display series—"Exoplanet Terrains"—that repurposed minifigure-scale LEGO sets with custom planet halves and printed landscapes to represent well-known exoplanets and speculative surfaces.

Luca's process shows how collectors and hobbyists monetize mods by offering limited runs and build instructions. He uses official LEGO pieces to ensure compatibility and sells decal packs and step-by-step PDFs to other AFOLs.

Takeaways from Luca’s model

• Start with a modular LEGO set that has neutral pieces and a sturdy baseplate.
• Design custom elements (like crater halves) as third-party 3D prints and produce them in small batches via a local resin printer or a print-on-demand service.
• Respect intellectual property: clearly label custom elements as third-party and follow LEGO fan project guidelines to avoid commercial conflicts.

Customer Story #3 — Priya: turning Wingspan components into an Exoplanet Discovery Card Game

Tabletop gamers often have superb craft skills. Priya, a game-night regular in Seattle, rewrote a friend’s Wingspan expansion into a compact exoplanet discovery game—what she calls "ExoSpan." Using Wingspan egg tokens, habitat mats, and card sleeves, she built a game that teaches discovery methods, habitability metrics, and mission types.

Her game uses card-sleeve inserts so the original components are preserved—this approach is classroom-safe (no permanent alterations) and reversible.

Mini-tutorial: Convert Wingspan pieces into a teaching game (ExoSpan concept)

Estimated time: 3–6 hours. Difficulty: easy to medium. Budget: $20–$70.

1. Materials: Old Wingspan or similar board game components, card sleeves, cardstock inserts (printable templates), sticker sheets for small icons, foam tokens for habitability points, and a rules sheet.
2. Create cards: Use free templates for planet cards showing radius, orbital period, star type, atmospheric notes, and a discovery 'method' icon. Print on cardstock, trim, and insert into sleeves over the original cards (so the edit is reversible).
3. Resource tokens: Use egg tokens as energy/resource markers—recolor with removable vinyl or use custom vinyl stickers to indicate water, atmosphere, or biosignature potential.
4. Gameplay: Players draft missions (like transit surveys, radial velocity, direct imaging) and spend resources to upgrade instruments—successful missions reveal new properties. The objective is to score points by confirming habitability criteria.
5. Educational layer: Each revealed property comes with a two-sentence teacher note on the back of the card, citing discovery technique and real exoplanet analogs (e.g., TRAPPIST-1e, K2-18b).

Priya’s version plays as a cozy game night filler and as a short classroom activity to teach discovery biases and methods.

Customer Story #4 — Sam: Sanibel shells repurposed into planet-surface texture studies

Sanibel (the new shell-collecting game) inspired Sam, a museum educator in Florida, to reuse the game's shell tokens and tactile bags to teach geologic processes on exoplanet analogs. Sam’s tactile station uses different shell textures and painted resin shells to represent surface geology—students match geological processes to textures as a sensory learning exercise.

Sam’s approach is inexpensive and inclusive—especially useful for classrooms with mixed visual abilities.

How to plan your own mod: practical checklist

Start by defining your goal—visual display, classroom lab, gift, or small-run product—and then follow this checklist:

• Scope: Display only, interactive demo, or playable game? Keep scope narrow for your first project.
• Scale: Minifig scale (LEGO), card game scale (tabletop), or shelf scale (diorama)? Scale determines print sizes and costs.
• Fidelity: Artistic impression or data-driven? If data-driven, select source images (JWST public images, NASA Exoplanet Archive) and create decal maps that match planetary color and albedo.
• Materials & tools: LEGO parts, Technic elements, 3D prints, resin casting supplies, waterslide decal paper, airbrush/paints, electronics (microcontroller power, servos), adhesives, and safety gear.
• Budget: DIY starter mods can be <$50; advanced 3D-print + electronics assemblies can run $200–$600.
• Time: Expect iterative builds—allow 1–3 weekends for a modest project.

Advanced technique primer (3D printing, resin casting, and painting)

For collectors who want museum-level finishes, here are condensed, actionable tips from pros in our community gallery.

3D printing hollow planetary spheres

• Model: Create a hollow shell with a 2–3 mm wall thickness and split it into two halves or a seam that fits to a bayonet lock. Add small 2–3 mm pegs for alignment before printing.
• Printer choice: MSLA for smooth surfaces; for larger spheres, print in PLA on an FDM with 0.12 mm layer height and then sand and prime thoroughly.
• Post-processing: Sand, prime with grey filler primer, and if using waterslide decals, coat with a thin gloss before decal placement to prevent silvering.

Painting & texturing

• Use an airbrush for base gradients (hot Jupiters show intense rim lighting; temperate rocky worlds have subtler transitions).
• Dry-brush for crater highlights, use thinned enamel washes for shadow definition, and seal with matte or satin varnish depending on the desired reflection.
• For ocean worlds, use layered gloss varnish and tint the lower layers slightly darker to create depth.

Resin casting for duplicates

1. Create a silicone mold around a master sphere half. Use a food-safe or hobby silicone—add casting keys for alignment.
2. Cast in a thin-cured epoxy resin, tint as needed, and demold carefully. Sand and paint as above.

Legal and ethical pointers

When you mod commercial products, be mindful of IP and safety:

• Follow LEGO fan project guidelines: avoid presenting your mod as an official LEGO product unless you have permission, and don't use LEGO logos for resale packaging.
• For board-game mods, avoid permanent alteration of base-game components that you may want to resell or return. Use sleeves, removable stickers, or replaceable tokens.
• If you plan to sell decals, 3D prints, or finished models, clearly mark them as third-party and list any non-official parts. See our guide on how microbrands price limited-run game merch.

Sharing and scaling: from hobby build to classroom kit or micro-business

Community mods often scale into micro-businesses. Here’s how hobbyists in our gallery did it legally and sustainably:

1. Open-source instructions: Publish free step-by-step PDFs and accept donations—this attracts learners and builds trust.
2. Paid extras: Offer decal packs, pre-printed card insert bundles, or small resin-printed elements for sale. Keep finished LEGO-compatible parts clearly labeled as third-party.
3. Workshops and school packs: Package classroom-ready kits (one teacher demo + 20 student mini-activities) and include a teacher guide aligned to NGSS-style standards for inquiry-based learning. Use a micro-event launch sprint to pilot kits locally.
4. Gallery & community: Host a user gallery on your site or a shared platform (Printables, Thingiverse, or exoplanet.shop’s user gallery) and encourage tagging: user_gallery, maker_community, community mods.

Safety and classroom compliance

Resin, solvents, and electronics require safe handling. Follow these rules:

• Use gloves and respirators when handling uncured resins; ensure adequate ventilation.
• Verify small parts are age-appropriate—label kits for recommended ages (e.g., 12+ for small pieces and resin-cast parts).
• Comply with school policies on non-official electronics. Provide pre-programmed microcontrollers or simple plug-and-play units for classroom ease.
