It takes a bit of force to separate them. E.g., I plugged a cable into Micro USB and added weights for a total of about 63 g so that the PCB would be pulled down and push against the bottom shell. Then, holding Anelok by the top shell, I had to shake it a little before the two case parts separated. > How do you intend to hold them together? With > screws or glue? Or did I miss some snapping parts? The friction between the side walls is strong enough to keep it together under light mechanical stress. I can even vary that by changing the clearance between the walls. The force comes from the case parts flexing and can be quite strong without producing much of a curvature. But in the long run I don't want to rely just on that. I think 2-4 screws would be best to keep things safely in place. The snapping mechanisms common in industrial products need undercuts, which are something I can't make easily with my mill. A 4-axis mill could do such things and with either a 4-axis mill, a precise double-sided process (mine isn't), or a multipart (> 1) mold (to be investigated) could do something like described here: http://www.grzsoftware.com/blog/how-to/machine-undercuts/ - Werner _______________________________________________ Qi Hardware Discussion List Mail to list (members only): [email protected] Subscribe or Unsubscribe: http://lists.en.qi-hardware.com/mailman/listinfo/discussion
