1. A Customization VarSet allowing creation of any size bin.
2. A Standards VarSet which includes all the dimensions from the original Gridfinity specification. These dimensions can be altered to suit your needs, and the bodies remain fully parametric.

4. A macro is included for the mass creation of labels. Recommended use in order to keep file stable.
