This is really great, thank you for doing this. Tangentially, while browsing through your blog I found this: https://www.mattkeeter.com/projects/machined-pen/the_plan.jpg https://www.mattkeeter.com/projects/machined-pen/the_plan.jp... This illustrates beautifully an idea that's been rattling around in my head for a while: what if the process you went through to design this manufacturing plan was the user facing cad api? When I approach a "making" problem--whether it's carpentry, plumbing, metal fabrication, machining--I naturally think about it in much the same way you did here. What raw materials am I starting with? What tools do I have? What sequence of operations do I need to perform to achieve the desired end result? The "cad api" (literally an api in the case of code cad tools or the visual representation thereof in traditional mouse driven interfaces) does not work this way, and forces me to think about how to represent the finished shape not about how I'll actually make it. All I care about in the end is making a thing, the modeling is just a tool to assist in that process but it makes itself way too visible. Naively it seems like there would be so many benefits to having a more "reality based" modeling workflow. As someone who clearly has a lot more experience in the cad space than I do, do you think this concept could go anywhere or is it a dead end? EDIT: also, a bit of feedback on the pen: you can maintain concentricity if you do something like this: 1. grab the bar stock in a 3 jaw chuck and turn it to a dimension suitable for a collet 2. cut off three blanks from the dimensioned rod, one for your cap and two for the body 3. do the rest of the work using a collet for work holding The tradeoff is you'll waste a bit this way if you want a different final dimension than you have for your collet.
