I need to create a rivet that will hold 2 3mm acrylics and 1 or 2 3mm felt pieces. I'd like to create it with acrylic or metal. Can anyone point me in the right direction for a tutorial or assistance? They should be 2 pieces that fit into each side and snap together inside the middle. My pieces are like sandwiches. 1 acrylic, 1 or 2 felt and 1 acrylic. I have tried to create rivets from sterling and niobium but am having no luck. I'd like to continue using the laser cut materials here.
