Snap-fit joints are a quick and easy way of connecting two 3D printed

There are 2 main types of snap-fit connections that are appropriate for 3D printing: cantilever and annular.

The cantilever is the most common snap-fit joint and consists of a protrusion (some type of bead or hook) at one end of the beam and a structural support at the other end

The radius of the fillet should be at least of 0.5x the thickness of the base of the cantilever

the clip should be at least 5mm wide

For FDM a tolerance of 0.5 mm is recommended

Use a 0.5mm tolerance for FDM snap-fit connections and 0.3mm for all other 3D printing processes.
