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.
The precision-molded slots of the rack ensure a secure fit for your test tubes, preventing spills and breakages. Its compact size makes it easy to store and transport, while its sleek design adds a modern touch to any laboratory.
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.
The design is not perfect and can definitely be improved, but it does its job well. Maybe some day I will find the time to improve it.
Cyanoacrylate can be used to secure the two pieces together, or you could also use melted filament.
