MakerBot replicator2 button - pla / abs (no need for fancy flex material)

Get an old tv remote .
dissect it to get the buttons ( made of silicone and on the opposite side there is a small black material that can conduct electricity )
Cut 5 of these buttons black round pieces. ( need a sharp utility knife )

After printing - use "super glue" (with latex gloves) to connect the tiny black conductive rubber to this button's back side - the are special grooves for the glue.

Be careful - not to cover the conductive side with glue as it may not conduct.

Enjoy :)
