- screw holes toggle - renamed base file to utility to avoid confusion - base dividing will now always be safe to use on baseplates (cannot divide into sections that cannot be multiplied by an integer to equal 1)

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
