I’ve created a hexagonal sprue test card designed to help you determine appropriate sprue dimensions based on your 3D printer’s output conditions!

Each sprue section is available in four different widths (1.0, 1.5, 2.0, and 2.5 mm) and can be tested at four varying thicknesses (1.0, 1.5, 2.0, and 3.0 mm).

By using this test card, you can determine the sprue thicknesses and widths that best suit your specific printing conditions, all while maintaining a stable support for your parts.

If you plan to design and 3D print your own model kit parts, this resource will help you choose the optimal sprue dimensions!
