Foldable Test Tube Stand

In a bio-chemistry laboratory, a test tube and test tube racks are as common as a pencil and an eraser in an art studio. But test tube racks can take up a lot of space not just while storing but even while experimenting. This foldable test tube rack aims to solve this major issue and make the laboratory space clutter free, making the lab more SAFE to work in.This design was tested and validated in the University of Plymouth, UK by technicians and scientists working in the university.Print Parameters :Material - PETG (PLA can be used but these test tube stands are used for hot water baths with the maximum temperature being 50 degrees so PLA can deform)Layer Height - 0.2 or 0.24Walls - 5Infill - 25% Gyroidmake sure you disable fill gaps or gaps smaller than 1mm<img src="https://makerworld.bblmw.com/makerworld/model/DSM00
