This 3D model is a test tube rack that I made for a genetic laboratory. It is designed to hold test tubes of two different sizes - approximately 18mm (30pcs) and 31mm (20pcs) in diameter. The rack is lightweight, durable, and can be used repeatedly.

If you work in a laboratory or conduct scientific experiments, this test tube rack can help you keep your test tubes organized and easily accessible. Simply 3D print the model using your preferred material, and you'll have a useful tool to streamline your laboratory workflow.

Cyanoacrylate can be used to secure the two pieces together, or you could also use melted filament.
