You will need the following parts to assemble one dodecahedron speaker:

9 x standard dodecahedron module
3 x dodecahedron module with holes for cables and mounting
60 x hexagon nut M4
60 x threaded bolt 4 mm x 16 mm (head of the bolt needs to have a diameter < 7 mm)
12 x speaker DAYTONAUDIO ND91-4 with sealing tape
3.5 m sealing tape for mounting between the modules
48 x tapping screws 3.5 mm x 9.5 mm (screws for mounting the chassis on the modules should be < 10 mm)
2 m speaker cable for connecting the chassis with each other
1 x speaker cable for external connection

If you use 4 Ohm chassis, you can connect three parallel connections of four serial connected chassis to get an overall impedance of 5.33 Ohm.
