Summary https://www.instructables.com/... IMPORTANT: For the inner molds "E27 Mold" and "buttonmold" make sure that you DONT print them with more than 5% infill, and DONT use more than one perimeter as in the picture above. The reason is that it should be easy to break the inner mold after the concrete has cured.
