I ended up completely redesigning the printer twice, trying to iron out flaws and make it ideal. Unfortunately, over my iterations I lost a lot of motivation. 3d printers are by no means a solved problem, but it felt like I wasn't bringing much to the table. The project was expensive, time consuming, and ultimately served to produce a machine outmatched by new offerings on the market- like Bambu's at the time new X1C.
In the end, I still took away a lot from that project in terms of CAD design knowledge, mechanical engineering, and 3d printing in general. I don't regret the work I put into it, and still tinker with 3d printers to this day.
