What Can You Upload?

You can upload files for replacement parts, prototypes, brackets, mounts, adapters, custom business items, logo displays, decorative models, hobby pieces, and product samples.

If your file is not ready for printing, we can review whether it needs repair, scaling, orientation changes, wall-thickness adjustments, or custom modeling support.

When to Use Instant Estimate vs Custom Quote

Use Instant Estimate

Best when your model is ready to print and you want a fast starting price for a standard custom 3D printing project.

Use Custom Quote

Best when your project needs file repair, 3D modeling, rush production, special material, tight tolerances, or manual review.

Before Uploading Your STL File

1

Check Scale

Make sure the model is designed in the correct size and measurement units.

2

Check Wall Thickness

Very thin walls may be fragile or difficult to print depending on material.

3

Include Details

Tell us the quantity, color, material preference, deadline, and use case.

4

Request Review

If the model is complex or functional, a manual quote may be more accurate.
