Easy assembled Geodesic Dome

Description

500 mm diameter Geodesic Dome Desing considerations The pieces are designed for a 3 mm diameter bar. It has a M3 screw to tight the upside and downside piece of each node. The distance between the theorical vertex and the end of the bar is 7 mm, this distance is called Lhole in the fantastic dome calculator by SimplyDifferently.org https://simplydifferently.org/GeodesicDomeNotes?page=3#2V/L2 In fact, you can change the diameter of the dome varying the long of the bars, feel free to play with this calculator. If you need different bar diameter, you can scale the piece for a factor, you have to keep in mind that the diameter of the screw and the Lhole will be affected for the same factor. Bill of materials: 20 pieces Hexagonal node 6 pieces Pentagonal node Cut wood bars, I made from skewers 30 bars 123 mm 35 bars 141 mm Screws 26 bolt M3x16 DIN912, nuts and washers. How to assemble 1 - Assemble all the pentagonal nodes with all the shorter bars 2 - Join the 5-point stars with hexagonal nodes. The hexagonal nodes has a notch pointing to shorter bars. 3 - Now we can take longer bars and assemby with hexagonal nodes See attached photos and floor plan.
