I think I might go in the direction of the duct tape. Duct tape and screws! Brilliant ideas. I also found some speculation elsewhere that holding back a bit of the flour might be enough to let the press stay in one piece. But @andiesenji and @Toliver, does this mean that you don’t think a pastry bag could work for all these traditional spritz cookie shapes?
I can’t imagine it, but I am a pastry bag innocent. All I’ve ever done is pipe some icing.
