This material would be difficult to make on your own without some pretty good woodworking skills. There are, however, similar, far less expensive sets of geometric solids for sale online that were designed to be used in math classrooms. These are a bit smaller than the Montessori version. Neither set has an ovoid, but as the author of one blog pointed out, an ovoid might be easy to find in a craft store after Easter.
