The primary source is an article titled "5 things I wish I knew when I started 3D printing smart home enclosures," authored by Sammy Ekaran, which offers practical advice derived from his experience with 3D printing, especially for creating housings for electronics. The article focuses on five key lessons: the importance of material selection for durability and heat resistance, the criticality of tolerances to ensure parts fit together correctly, the time-saving nature of using test prints before a full production run, the value of post-processing techniques to improve the look and function of the prints, and how layer orientation significantly affects the final part's strength. Following the main text, several reader comments are included, adding cautionary notes about toxic fumes from certain filaments and debating the implications of using materials like PLA for enclosures that could potentially overheat. https://thebusinessofmanufacturingpodcast.podbean.com/
