You've completed the design. You have the instructions and parts list. The next challenge is finding hundreds or even thousands of individual bricks in the correct colors and quantities.

This is especially useful for large or complex MOCs where individual parts sourcing can become time-consuming and difficult to manage.

From Digital Design to Physical Parts
A custom MOC is more than a digital design. The physical build also requires parts sourcing, inventory management, sorting, preparation and quality checking.
With structured parts-handling workflows and production support, Letbricks can help customers move from an idea or parts list toward a complete physical building set.
These capabilities also allow us to evaluate larger B2B and batch-production projects.
Parts Production Support
Production resources help support projects that require larger quantities or repeated parts requirements.
Efficient Parts Sorting
Structured sorting processes help us prepare large and complex parts inventories more efficiently.
Manual Inspection & Preparation
Manual handling and checking remain an important part of preparing custom and small-batch projects.
Why Work With Letbricks?
Custom brick projects often involve much more than simply creating a digital model.
MOC-Focused Experience
We work with MOC designers and builders and understand the workflow from digital inventory to physical build.
Large Parts Inventories
We can review and prepare parts requirements for both smaller projects and extremely large MOCs.
Design + Parts Support
Customers don't necessarily need to find a designer and parts supplier separately.
Personal & B2B Projects
We accept personal custom inquiries as well as professional and larger business projects.
