Is it possible to set a page as child of a custom post type slug?

I have the following sructure: /projects (archive of cpt 'projects' with template archive-projects.php) /projects/project-1 (single view of cpt with template single-projects.php) /projects/downloads (this is a page)

When I try to open /projects/downloads I get an 404 error. Is there a way to set a page in the cpt hierarchy?

Thanks! Aldo
