Test Tube Holder/Rack: A Versatile Design for Storing Multiple Tubes Crafted to accommodate a large collection of test tubes, this holder/rack boasts various innovative designs. A few models feature delicate string-like arms that grasp the test tubes securely, though one particular design struggled with printing issues. The majority of the designs, however, have proven remarkably effective in conserving filament by incorporating strategically placed holes. This clever approach not only saves material but also ensures a seamless print without the need for supports.
