Do any of you know of a workshop/bootcamp for learning to make + manufacture + distribute physical products on a small scale?

Maybe something a bit like Bolt’s Groundwork workshop, but less startuppy and perhaps more practical, plus… still exists? https://web.archive.org/web/20230313123137/https://groundwork.live/

(Boosts outside of my normal less-physical-and-more-digital audience appreciated.)
