10cm Heart to make mold for casting

If you gonna make mold from this, there is on other side a hole so you can pull string through it so it should make it easier pulling when silicone (or other molds) will get solid.

SEMS is a tribute to southeast makerspace thanks to whom I got introduced to 3D printing. Plus we intend to use these parts our-self so it's nice to have own branding.
