About this model

I looked at a test tube rack yesterday and thought it would be easy to design and print one. So I did. And it was. Model in the picture was printed in school colors at 75%, I wouldn't go any smaller or the test tubes won't fit. If you use test tubes in the lab it would be a fun project to have the students design their own for use during the year.
