Tooltrace is an easy-to-use web app that generates custom Gridfinity bins with a perfectly shaped cutout (i.e., a tool negative) to place your tool into. Unfortunately, more advanced customizations are lacking. GridfinityGenerator offers several advanced customization options, such as placing magnets on the bottom of the bins. However, to generate a bin with a custom cutout, you need a (positive) model of your tool. Creating a (positive) model of your tool is much harder than using Tooltrace. This web app aims to take a bin with a cutout generated on Tooltrace, and produce a tool (positive) that can be used in GridfinityGenerator.
