Geodesic sphere. At this scale the completed model is around 32 cm in diameter.

You will need: 60 x 16mm M6 nuts and bolts or suitable equivalent. 12 x Pentagon cut outs (preferably 3mm acrylic). or similar thickens material. 20 x Octogon cut outs (preferably 3 mm acrylic) or similar thickness material.

The one i have made has an opening section consisting of one pentagon attached to 5 octagons, with magnets attached into some off the printed parts and washers glued to the 3mm profiles. If you intend to do this then you will need: 5 x stl parts 3-11. 45 x stl parts 1-2.

If however you intend to make a complete sphere with no opening section you will need 60 x stl parts 1-2

All the printed parts have a circular witness mark on one of the arms top and bottom sections. this arm should always be connected to the pentagon profiles as the angle is ever so slightly different to the arms attached to the octagons
