Description

Latest revision added new parameters and colors selection

I created this model generator to practice and get more familiar with OpenSCAD.

I’ve always been fascinated by 3D ambigrams, so I wanted to explore how they are made. I started with a single letter

letter1 = "S";
letter2 = "M";
size = 40;
font = "Overpass Mono:style=Bold";

intersection() {
//letter1
linear_extrude(center = true)
text(letter1, size = size, font = font, halign = "center", valign = "center");

//letter2
rotate([0, 90, 0])
linear_extrude(center = true)
text(letter2, size = size, font = font, halign = "center", valign = "center");
}

And gradually worked my way up to creating a simple word, such as:

string1 = "LOVE";
string2 = "HATE";
size = 30;
font = "Overpass Mono:style=Bold";

rotate([90, 0, 0])
for (i = [0 : min(len(string1), len(string2)) - 1])
translate([i * size, 0, 0])
intersection() {
// string1
rotate([0, -45, 0])
linear_extrude(height = size, center = true)
text(string1[i], size = size, font = font, halign = "center", valign = "center");

// string2
rotate([0, 45, 0])
linear_extrude(height = size, center = true)
text(string2[i], size = size, font = font, halign = "center", valign = "center");
}

Step by step I added more parameters, a base, and other refinements, while keeping it simple.

The full source code is included so everyone can experiment and generate their own custom models.

string1 = "LOVE";
string2 = "HATE";
angle = 45;
font = "Overpass Mono:style=Bold";
size = 30;
spacing = 1.1;
baseThickness = 3;
baseRound = 20;

step = size * spacing;
nChars = min(len(string1), len(string2));
modelLength = (nChars - 1) * step + size;
baseR = min(baseRound, (size / 2) - 0.01);

module letterChar(char, tilt = [0, 0, 0]){
upperChar = (ord(char) >= 97 && ord(char) <= 122) ? chr(ord(char) - 32) : char;
rotate(tilt)
linear_extrude(height = 2 * size, center = true)
text(upperChar, size = size, font = font, halign = "center", valign = "baseline");
}

translate([-(nChars - 1) * step / 2, 0, baseThickness])
rotate([90, 0, 0])
for (i = [0 : nChars - 1])
translate([i * step, 0, 0])
intersection() {
translate([-size/2, 0, -size/2])
cube(size);
letterChar(string1[i], [0, -angle, 0]);
letterChar(string2[i], [0, angle, 0]);
}

linear_extrude(height = baseThickness)
offset(r = baseR)
square([(modelLength + size / 2) - 2 * baseR, size - 2 * baseR], center = true);
