Thanks to @Vallerie Guzman for requesting this video! Do let me know if you're looking for drawing 3D structures of molecules with higher steric number like octahedral, T-shape, etc.
Great video. Only one remark. The lone pair in a triagonal pyramidal structure offers greater repulsion. This means that for ammonia NH3 the angle would be 107 degrees. In the case of this video where NF3 is used, fluorine is more electronegative than hydrogen and therefore there is even greater lone pair repulsion making the angle 102.5 degrees.
