Wouldn’t it be nice if you could simply press-fit your LilyPad Arduino to your fabric circuit traces! That you could sew your circuit with the sewing machine using conductive thread and not have to do all the hard-soft connections by hand! Here some experiments in making a 3D printed LilyPad SnapRing that connects in this way…
