How to Sell LEGO MOC Instructions Online

When designers sell a MOC, they usually sell digital building instructions rather than the physical bricks. These instructions typically include a step-by-step guide, a parts list, and sometimes additional information such as recommended substitutions or building tips.

Most designers use digital building tools to create their models and instructions. Software such as BrickLink Studio allows builders to design models digitally, generate part inventories, and export professional instruction manuals. These tools make it possible to prepare a MOC for distribution online.

Once instructions are ready, designers typically publish them on specialized platforms. These marketplaces allow builders to upload instructions, set prices, and distribute digital downloads.

LEGO-Focused Platforms

• Rebrickable – a well known platform where builders share and monetize instructions while connecting models to official LEGO sets and part inventories.
• BrickLink Studio – widely used as a digital design tool for creating LEGO models and generating instruction manuals and parts lists.

Our Platform

• OpenStuds – a marketplace designed for independent brick designers. Unlike LEGO-specific platforms, OpenStuds allows creators to publish instructions for builds using any compatible brick systems or custom building techniques. This makes it suitable for experimental designs, alternative brick brands, and niche building projects that do not fit traditional platforms.

Getting started usually follows a simple process:

1. Design your model using a digital building tool.
2. Generate instructions and a parts list.
3. Create preview images of the finished model.
4. Upload the instructions to a marketplace.
5. Set a price and publish your listing.

Once published, builders around the world can download your instructions and recreate your design with their own LEGO parts.

Successful MOC designers often build an audience over time by publishing multiple designs, sharing their work on social media, and engaging with the LEGO fan community. Consistent releases and clear instructions help establish trust with builders who want to recreate your models.
