Description

This is a Test Tube Holder I created for my open source 3d printing class, it should hold 12 test tubes that are 16mm in diameter and can be assembled at different heights for various test tube heights. It also has other top parts that can slot in so that this design can hold smaller and larger test tubes and other similar sized devices.
