Customizable Engraved Rings

This is an OpenSCAD customizer for creating an engraved ring. Specify the inner diameter, the width and the thickness of the ring. It can be sized large enough to make a bracelet. Add text inside, outside, or both. Choose from 20 pre-selected fonts or enter your own. The fonts are shown in the center area of the first image, as a guide to help you choose a font that you like.

There are two sample STLs included: one with a very large and a very small ring demonstrating the size variance, and one with "♥ My Love ♥ Forever ♥" inscribed on the inside demonstrating that special characters can be printed.

You can consult the International Ring Size Conversion Chart if you know your ring size and need to convert it to millimetres.

Note that although the text spacing is a parameter that you can set, it is automatically increased above the set value so that exactly an integral number of characters fit around the perimeter. So as the text spacing is increased or decreased, you won't notice any difference until one less or one more character can fit with the specified text spacing.

Running the Customizer

Thingiverse hadn't run their customizer queue from Jul 10, 2020 to Aug 4, 2022 and may stop running it at any time again, so if they don't process your customized job, you will have to install and run OpenSCAD (free software) on your own computer to process the code to create your own customized models. See DrLex's instructions linked below for further details.

How to Run Customizer on Your Own Computer

You can use any font available on your system. The OpenSCAD "Help=>Font List" menu item shows what fonts are available. Most of the fonts listed in the drop-down selection for this thing can be downloaded from: Google Fonts repository

To make a font available to OpenSCAD you have three options:

1. Install the font to the system. The procedure for installing system fonts is dependant on what operating system and what version you are using (Ubuntu Linux 16.01, Ubuntu Linux 20.04, Windows 7, Windows 10, Mac OS 9, Mac OS X, etc. ). If you don't know how to install a font on your system then search the web for instructions.
2. Add the font file to your fonts folder, creating the folder if it doesn't already exist. On Linux this would be something like "/home/YOURUSERNAME/.fonts" and on Windows 10 it would be something like "C:/Users/YOURUSERNAME/.fonts".
3. Add the font to the folder that contains the OpenSCAD file that you want to use the fonts. You will also have to add to the OpenSCAD file the 'use
