Summary of Inventorium Tank (June 2020)

Summary of Inventorium Tank on June 26, 2020 written by CEO Steve Ring. Inventors discussed their newest products in development with the Inventorium. Investors are welcome.

Slim Z Bracket

Steve Ring invented the Slim Z Bracket while developing prototypes for another Inventorium idea. Unable to find the right piece of hardware in stores, he designed his own.
