I want to make wristband at home. I intend to cast commercially available casting silicone into 3D printed form.The question is, what material to choose to have the wristband flexible, long living and waterproof in contact with plastic insertions depicted. Also, maybe you have idea how to have a flexible PCB inside wristband available for insertion's contacts inside holes.https://ift.tt/2AbGJov via /r/DIY https://ift.tt/2yHNVHe
