From Passion to Precision

The gruvTube™ was born from a love of live music, a dedication to preserving show posters, and an endless curiosity to learn. Fueled by these passions, I taught myself mechanical engineering via youTube and worked through over 50 design iterations to create the perfect poster tube end caps. What started as an idea has become a reality, combining form and function to help your art travel like never before.

Watch as the first version of the gruvTube™ comes to life in this 3D print build.
