From e8babd7912a78277bd595969ae7c0435bb74b1a9 Mon Sep 17 00:00:00 2001 From: kennetek Date: Sun, 18 Sep 2022 11:07:33 -0700 Subject: [PATCH] gridz can now equal zero if only base is desired Setting gridz to 0 (or anything less than zero) will only generate the base pattern. This is useful in cases where you want to use those wonderful printable holes on other models. --- .gitignore | 2 +- README.md | 2 +- gridfinity-rebuilt-base.scad | 12 +++++++----- 3 files changed, 9 insertions(+), 7 deletions(-) diff --git a/.gitignore b/.gitignore index ea4d15d..df767b3 100644 --- a/.gitignore +++ b/.gitignore @@ -1,4 +1,4 @@ ignore/ gridfinity-rebuilt.json -stl/ \ No newline at end of file +stl/ diff --git a/README.md b/README.md index 48549bf..caef9d0 100644 --- a/README.md +++ b/README.md @@ -36,7 +36,7 @@ Parameter | Range | Description `gridx` | {n>0\|n∈Z} | number of bases along the x-axis `gridy` | {n>0\|n∈Z} | number of bases along the y-axis `length` | {n>0\|n∈R} | size of the square bases in millimeters, default 42 -`gridz` | {n>0\|n∈R} | height value (can be interpreted in various ways) +`gridz` | {n>=0\|n∈R} | height value (can be interpreted in various ways) `gridz_define` | {0,1,2} | • (0) Unit height: `gridz` is the height in units (7mm increments). The stock bins have a unit height value of 2, 3, or 6. The overall height of the bin is `7*u + 3.8` millimeters, where the 3.8 is the height of the top lip.
• (1) Internal height: `gridz` is the height from the bottom of a compartment to the top of the tab in millimeters. This is effectively the maximum height of an object that can fit inside the bin.
• (2) External height: `gridz` is the overall height of the bin, from the base to the upper lip fillet.
