Building with lots of small parts gets messy fast. This modular brick sorter system was designed to keep pieces organized while you build, making the process easier, faster, and more enjoyable.

The system includes:

• A large sorter with dedicated slots for technic axles
•  A large area for general pieces and building on
• A compact 2×2 sorter for small pieces

All trays are fully modular and slide together using flange pieces, allowing you to print only what you need and expand the system as your collection or project grows.

Make sure to leave me a boost and a follow. Leave a comment if you have a suggestion on what could be improved!

It also makes a great gift for builders, hobbyists, or anyone who enjoys staying organized while working on detailed projects.
