The first iteration will use an existing thermally isolating container with a 3D printed lid. Almost every part of this project will be housed inside this lid, so that anyone already owning one of these popular thermal containers could add some fancy new functionality to his terere gear.

Getting the printed lid right and watertight might take a few tries, so this first attempt is just about finding out what parameters to tweak to get a perfect fit.

Clips to hold the pump and electronics are not yet included and the dispensing end has not been designed for now.
