Summary

Potassium, titanium, silicon and oxygen atoms for construction of Ivanyukite-K ball-and-stick model.
Model sizes (diameters):
K - 32.1 mm; Ti - 18.7 mm; Si - 16.0 mm; O - 14.7 mm;
Holes - 2.0 mm.

Example of final constructed model see on: https://skfb.ly/puryD

The bond lengths:
K--O - 60 mm (72 bonds);
Ti-O - 34 mm (96 bonds), 38.5 mm (96 bonds);
Si--O - 30 mm (48 bonds)

Due to the large number of oxygen atoms in the structure, all oxygen atoms are divided into two files (part1 and part2).
