// Gridfinity Bins With A Stacking Lip
// Gridfinity is a system to help you work more efficiently. This is a system invented by Zack Freedman. There are two main components the baseplate and the bins. The components are comprised of a matrix of squares. Allowing easy stacking and expansion. This Gridfinity bins version includes a lip to allowable stacking Gridfinity bins
