I want to print parts that can be assembled. I have no mechanical engineering background so I didn’t even know the relevant terminology. After a bit of research I learned that one way to do this is with snap-fit joints. I looked for design guidelines online on Google and amazon, figuring there must be well-known rules for how to design joints that are strong and reliable.
I found these great free PDFs, all by chemical companies:
- http://plastics.dupont.com/plastics/pdflit/europe/markets/L12565e.pdf (Chapter 9)
These books also seem to contain a lot of useful information (according to their amazon previews), but they probably go well beyond what I need, and they’re not cheap:
- http://www.amazon.com/Plastic-Part-Design-Injection-Molding/dp/1569904367 (Section 6.3)
- http://www.amazon.com/Designing-Plastic-Parts-Assembly-6E/dp/1569904014 (Chapter 8)
Feel free to recommend others if you know any.
