Rutile (TiO2)

Titanium and oxygen atoms for construction of Rutile ball-and-stick model.
Model sizes (diameters):
Titanium - 14.7mm; Oxygen - 13.4 mm;
Holes - 2.1 mm.

Example of final constructed model see on: https://skfb.ly/p9P6y
In this example, there are 9 Ti atoms and 40 O atoms.
The bond lengths:
Ti--O - 30 mm (36 pieces), 31 mm (18 pieces);
Ti--Ti - 46 mm (4 pieces), 71 mm (8 pieces)
