anorm/whetstone-guide

This project is a parametric 3D model for a whetstone guide, a small tool that helps someone hold a knife at a consistent angle while sharpening it against a sharpening stone. The design is built using OpenSCAD, a programming language for creating 3D models with code rather than a mouse and a modeling interface, which makes the guide fully customizable through parameters rather than manual editing of shapes. Users can adjust the width, height, and length of their specific whetstone, along with the length of the guide itself. The most useful feature is that the guide supports up to four different sharpening angles at once, each one optional and independently configurable, so a single printed guide can serve several sharpening angles depending on the knife or the stage of sharpening. To use the project, you open the source files in the scad folder either directly in the OpenSCAD application or by running a single make command, which generates both an STL file ready for 3D printing and a PNG preview image showing what the assembled guide looks like. The README notes a small but important distinction: when previewing the design, it shows the whole assembled guide together, while the actual render and print output lays the individual parts out flat, arranged the way they need to be for a 3D printer. This is a niche, practical repository aimed at people who own a 3D printer and want a physical accessory for knife sharpening rather than software or an application. There is no server, app, or code to run beyond generating the print files.
