Hello everyone! I am Daniel. The reason for most of my designs is my severely ill son Jan. Many designs were created out of direct necessity to enable my son to participate and experience joy. With severe epilepsy, visual impairments, and muscle weakness, most conventional toys or aids are often unsuitable or unaffordable. Not every model has a direct relation to my son's development. But they have helped us in family life. By downloading or "liking" my models, you support future projects for Jan.
