What im doing:
So I am designing a pendant to give to my girl friend. It will be the first thing I print on shapeways. The idea is the pendant will hold a message on a piece of paper wrapped around a pin inside. The pendant will be two parts and made of sterling silver. My CAD skills are more then adequate to produce the pendant, Im using solidworks.

The problem:
Im not sure what specs I should give the screw thread. So i wanted anyone's advice on the pitch, clearance and size of the thread. The nominal diameter is 4mm. The pendant is pictured both with a cross section and with out. I have read the material data sheet, but the minimum detail of 0.6mm isn't as much clarification as i would like.

Any help or feedback would be appreciated as im looking forward to doing more projects through shapeways.

This is just an idea, but what about having a pin lock? I couldn't find a picture of an example, so I uploaded a quick concept.


The transverse pin is inserted and turned clockwise to lock - it would be ideal to have some sort of detent so it would stay locked.

As for your idea, i do like edison sockets, i should have thought of that.

i left a gap of 0.1mm between the threads, i hope thats enough for the tolerances.]]> 6516440 2012-04-26T06:13:05-00:00 http://www.shapeways.com/forum/index.php?t=rview&goto=47526&th=9167#msg_47526
