Not mine, but I thought it was a good example of concepts that affect hobbyist 3D printers specifically. In this case build size. At first glance build size seems like a liability. But sometimes it can turn out to foster things you just don’t find in IRL stores anymore. Things like modularity and portability. This particular project is one 4-way flat clip and one 2-hole linear clip away from being infinitely expandable and portable…

and maybe a 3way and 6 and 8 way for partitions. the clips need an OpenScad project.
