In this version, the tea light holder has a lower open spherical shape so that it can be used with a regular wax tea light.
Further down are the 4 versions of the straight flared tea light holder that are also well suited for use with a tea light.
Of course, an electric tea light is also very suitable for use with these designs.
[ NB: A design for a holder for an electric tea light with a higher inward-facing rim is in the other article. That version is not suitable for a tea light with a flame, because a flame can distort the higher, more inward edge.]
Print these STL files on a suitable 3d-printer with heat-resistant, fairly transparant filament for best effect!
