The file 'Watch Caseback / Crystal Die 3D Printer Model' is (stl) file type, size is 22.5KB.
This is a die I designed to remove the crystal from my Seiko V158 though I'm sure it could be used for other watches. The press portion is about 21mm in diameter and the holder will clear a crystal diameter smaller than 33mm.
