Here's an idea: Maybe look around for You Tubers who are creating one-off 3d models and pitching them to do a product run. If you want to see what something like this could look like, Aaron Parecki designed a very clever stand for a video device called an ATEM Mini, and started with one-off 3d prototypes he was printing. He validated the idea, then sourced up to a small -- just a bit bigger than a garage -- "factory" that would be like what you're describing. Here is a tour of the "factory" https://youtu.be/ljaEnoJZ8OY?t=1071 https://youtu.be/ljaEnoJZ8OY?t=1071 Might help you source ideas by looking at what some creators are prototyping on their channels, then pitching a small scale factory run of the devices.
