HI Theuns, Off course you do not have to make your own heart.stl. Its is
the exploitable heart from emmet. http://www.thingiverse.com/thi... . I am sorry that it wasn't clear. Good luck!!
Do I need to make my own heart.stl file? I see it must be loaded in SCAD, which I use but have little experience with. When I Complile the SCAD file it makes a rectangular shape...
Depends on your printer and what you want to put in there. I printed it at 100%. It has thick walls so I got multiple perimeters for my 0,5mm nozzle. I had to fold the money pretty small to get it in there. The endresult is about tennisball size. If I would print it again I would probably change the scad file to get thinner walls.

You can use the openscad file to make your own versions. The hole in the middle is made with a scaled down version of the original shape. So a hollow Cube, Sphere and Heart will work. But for example a donut would not work. In the openscad file the size_hole_inside reflects how big the inside hollow shape is. You can use it to change the outside wall thickness. When it is 1 the hole is the same size as the whole product so you would not get an outside wall. If you do not want inside walls you set "withwalls" to false. The wall thickness is the thickness for the inside walls. I also put some code in the comments which put a B and a P in pieces 1 and 2. I included a P and a B stl, so if you happen to need a P and B you can make your own STLs for the heart-pieces.
The STLs for the heart-pieces are without letters.
For the STLs the one with walls is bigger as the one completely hollow.
I printed them on a Prusa mendel. After removing some small irregularities on the edges they fitted very well.
