Conical Test Tube Stand

thingiverse

This is a simple stand for the test tubes that are used for liquid samples in laboratories. This stand fits 50 ml test tubes with screw caps and a conical base. It is much lighter than many commercial holders, which makes it especially suited for accurately measuring out compounds using a lab weight scale, since these have a limited capacity. However, this comes at a cost of stability, so use with caution. It can be printed without supports, if placed upside down! Source code (.stp & .3dm) is also provided, should you want to modify the design for your own purpose. Please share your prints!
