Durable Holding Plate for Centrifuge Tubes

In my high school biology lab, and likely in other labs at various levels, there is a problem with how small centrifuge tubes are held. Sometimes they just need to sit on the table, and other times they need to float in water. Sometimes the holder needs to survive in high temperatures. Separate holders are often required for each task. Even more frustrating, the existing holders are weak and expensive. Printed out of ABS on any desktop printer, this holder is cheap, durable, survives high temperatures, and floats in water. It is about a quarter the cost of a holder ordered online for a much more durable design. Its abilities to be very hot and float make it ideal for baths in boiling water for various labs. It is also designed to stack, so multiple holders can be stored conveniently in a stack. The screenshot of the printing website proves that it can be printed. Services were expensive but on a desktop printer, the cost is low.Made by Spencer Williams from the Webb School of Knoxville
