You can't teach 3D/solid shapes using a flat poster! Print out these posters and attach you own solid shapes to each. Here are some examples of what I used, but I'd love to hear your ideas as well!
Cone: Party hat from the Dollar Tree
Cylinder: Empty soup can
Cube: Empty tissue box
Sphere: Christmas ball ornament from the Dollar Tree
You could also use these sheets in math centers to guide a 3D shape sorting activity!
