From broken replacement parts to brand-new ideas, LettWorks 3D turns photos, sketches, measurements and CAD files into functional custom parts.

You don't need to know CAD or own a 3D model. Send us what you have and we'll help determine the best way to make it.
Brackets, mounts, spacers, adapters, knobs, clips, covers and other one-off functional components.
Have a sketch, measurements or an idea? We can turn it into a manufacturable 3D model and prototype.
Can't find a discontinued or broken plastic part? Send photos and dimensions and we'll evaluate recreating it.
Already have an STL or STEP file? Send it over with quantity and intended use for a printing quote.
Need more than one? We can quote repeat parts and small batches without traditional tooling costs.
We can evaluate fit, geometry and printability and revise designs when a prototype needs another iteration.
A few examples of custom parts and practical solutions designed for real-world use.

Custom 10-position holder with a fitted outer cover, designed to keep a stamp set organized and protected.

A purpose-built household holder showing how a simple idea can be turned into a clean, printable part.

A straightforward custom tray for separating and organizing small parts, tools or everyday items.

A mechanical-style component with a cylindrical body, stepped features and mounting flange—an example of geometry built around a specific fit and function.
Getting a custom part made shouldn't be complicated.
Share a photo, sketch, dimensions or CAD file and tell us what the part needs to do.
If CAD work is needed, we create the model and work through the important details.
Your part is prepared and 3D printed using a material appropriate for the application.
We finish the part, verify the basics and ship it to you.
