Flat Pack Test Tube Rack

thingiverse

I stared at a test tube rack yesterday and figured designing and printing one would be a breeze. So I took on the challenge, and voila! It turned out perfectly. The model you see in the picture was printed in school colors at 75% capacity - any smaller wouldn't fit the test tubes properly. If your students use test tubes in the lab, it could be a fantastic project for them to design their own, which they can then use throughout the year.
