Modular Test Tube Rack

thingiverse

This revolutionary modular test tube rack offers unparalleled flexibility and customization options. Its adaptable design allows users to adjust the height, hole diameter, and capacity with ease. A major advantage of this cutting-edge design is its versatility, accommodating test tubes of every size, from smallest to largest, eliminating the need for multiple racks and the hassle of searching for a specific size. Standard test tube racks vary significantly in price, ranging from under $10 for compact units to over $60+ for larger models. In contrast, this customizable rack can be produced at an affordable cost of approximately $4, with only a minimal increase in expense for large-scale productions. Additionally, printing the rack with less than 25% infill further reduces the cost.
