Gridfinity stacking lip
What the lip is, how much height it adds and when you can leave it off.
The lip is the stepped rim at the top of a bin that lets another bin stack securely. Height units are 7 mm, and with the lip a bin measures 7 × n + 3.54 mm overall (a 3-unit bin is 24.54 mm, checked on the library STLs). Turn Lip off in the generator for a flat top.
