I think if you want to corner a new market, a machine that grinds plastic and extrudes filament maybe even winds it up. For snap maker. I can tell you its an easy machine to source and design, plus with you new found brand recognition, and simple interfaces, it could go a long way. There are $20 diys, and $4000 filament machines on the market so, the idea will fly. A bucket, and a new addon that heats to almost the same temps as Snapmaker (original), may be an adjustable nozzle. I get the prototype free though
