3D Printed, Snap Fit Enclosures

This week I brought my 3D printer out from the attic because I wanted to build some electronics enclosures. I’m fairly experienced with CAD and Fusion 360. However, my experience with building boxes is limited to laser cutting. This blog documents my first steps learning to build laser-cut enclosures and references to resources about building electronics enclosures using a 3D printer.

My first attempt at an enclosure failed because the connection pins failed to be able to enter their bosses. The pins were also too weak and broke off in the process of attempting to force them in. I realize now that I need some design rules for dimensioning parts to achieve these types of clearances.
