I have come to terms with the following: A well written blog post may be the only production capacity I realistically can produce. Who's gonna buy things this niche? and how many of them can I manufacture and sell anyway? pretty much zero. But a blog, maybe it gets used by people, to produce their own things. Distributed manufacturing and repair. Someday soon, the tables will turn and things wont be just used and thrown away as much, so my skills at any given time are my only product.
More 3d printers, and less e-waste.
