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.

IMPORTANT: rendering will be better for analyzing the model if fast-csg is enabled. As of writing, this feature is only available in the development builds and not the official release of OpenSCAD, but it makes rendering only take a couple seconds, even for comically large bins. Enable it in Edit > Preferences > Features > fast-csg
|
||||
the plane that is the top of the internal bin solid is d_height+h_base above z=0
|
||||
the magnet holes can have an extra cut in them to make it easier to print without supports
|
||||
tabs will automatically be disabled when gridz is less than 3, as the tabs take up too much space
|
||||
base functions can be found in "gridfinity-rebuilt-base.scad"

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

// Compartments can be placed anywhere (this includes non-integer positions like 1/2 or 1/3). The grid is defined as (0,0) being the bottom left corner of the bin, with each unit being 1 base long. Each cut() module is a compartment, with the first four values defining the area that should be made into a compartment (X coord, Y coord, width, and height). These values should all be positive. t is the tab style of the compartment (0:full, 1:auto, 2:left, 3:center, 4:right, 5:none). s is a toggle for the bottom scoop.
