Added different height specifications
Height can now be defined by the unit height, internal height, or external height. Added lip toggle. Added option to snap bin to unit height. Fixed small protrusion at the bottom of the outside wall edge that made the STL look less clean. Split file into base file and command file, to allow for ease of use and possible future module expansion.

BIN HEIGHT
|
||||||
|
the original gridfinity bins had the overall height defined by 7mm increments
|
||||||
|
a bin would be 7*u millimeters tall
|
||||||
|
the lip at the top of the bin (3.8mm) added onto this height
|
||||||
|
The stock bins have unit heights of 2, 3, and 6:
|
||||||
|
Z unit 2 -> 7*2 + 3.8 -> 17.8mm
|
||||||
|
Z unit 3 -> 7*3 + 3.8 -> 24.8mm
|
||||||
|
Z unit 6 -> 7*6 + 3.8 -> 45.8mm
