Recently I purchased a rather nice backpack which features an area that can hold velcro patches. I thought it would be nice to have one with my callsign on it and went hunting for one off emboydered patches. An idea occurred to me that a 3D printed banner could work. Here's the result:
Close up you can see that I've coloured in the engraved letters with a permanent marker. Some sort of paint would be better.
I'm able to write OpenSCAD code but it turns out so can Claude Code. This is what we came up with:
// Rectangular plate with embossed text
// Dimensions
plate_length = 90; // mm
plate_width = 20; // mm (adjust to taste)
plate_height = 2; // mm plate thickness
text_depth = 0.8; // mm how proud the text stands
rim_width = 1.5; // mm wall thickness of raised edge
rim_height = 1.0; // mm how tall the rim stands above the plate
// Base plate
difference() {
cube([plate_length, plate_width, plate_height]);
// Embossed text on top surface
translate([plate_length/2, plate_width/2, plate_height-0.6])
linear_extrude(height = text_depth)
text(
"VK3TPM",
size = 15,
font = "Liberation Sans:style=Bold",
halign = "center",
valign = "center"
);
}
