3d printing them myself makes them around $0.90 per cookie. Do you use a bunch of them or just a few? I have never used them. Recently, I printed a bunch of painting triangles. They are used to lift a piece from the work surface during a painting or finishing process. Any drips on the edges will drip off and not stick the piece to the table. Triangles are good for lighter pieces. They don’t hold the piece in place. There is not any friction. Here is where the cookies show their strength.
Shown below are a few cookies. Soon there will be some rubber circles glued on the top and bottom of the cookie. This will hold the piece still and also hold it up from the table. A key is to not put the cookies on the edge of the piece. Let the piece hang over by pushing the cookie under an inch or more.
