I bought this 5-piece set of hex drivers from AliExpress (https://www.aliexpress.us/item/3256802985732058.html?) but while searching Maker World I could only find a 4-piece organizer, or one for a whole lot more. I jumped on TinkerCAD, with a basic idea in mind (and inspiration from the others I'd seen) and threw this together. It was my first attempt at putting chamfers around holes.
