JSCAD is an open-source set of modular, browser, and command line tools for creating parametric 2D and 3D designs with Javascript code. It provides a quick, precise and reproducible method for generating 3D models, and is especially useful for 3D printing applications. There are different 'flavors' of JSCAD that you can use based on your needs. JSCAD is a solids modeling system. It is fundamentally unitless, however, when you export files, typically 1 unit in JSCAD corresponds to 1 millimeter in your model file. Modeling in JSCAD is often a case of building the shape you want out of primitives, but there are often many different options to get the same shape. Check out the examples on the JSCAD app's info menu to learn about the different capabilities. Booleans are one of the most important tools in the solid modeling toolkit. Many of the shapes that you will need to create on your journey can be created by joining, subtracting and intersecting simple shapes.
