Infinite Stairs sand mold

Inspirated by indian architecture
I decided to do a sand mold for my infinite stairs castle (see entry #929228). So this is the first try on a pyramid mold and a mold for one pair of mirrored stairs to decorate the pyramid. Both molds should be scalable and always in relation to another, so that the stairs fit exactly on the big pyramid.

• I made it customizable, see instructions for further information.

In contrary to my first entry of the fancy and huge infinite stairs castle, this would really be printable.

Follow up:

• My goal is that the molds are scalable together, in relation to another.
• I am trying to figure out how to do a mold for my linear extrusion tower, which sits on top of the infinite stairs castle. But this won't be easy, as the tower will sit in the mold like a screw inside a thread.
