E3D+VET exercise: Solar System

thingiverse

This is part of a series of 30 exercises developed during the E3D+VET program. The aim of this Erasmus+ program is to immerse VET centers in 3D printing (website: https://www.e3dplusvet.eu/).\r\n\r\nThis exercise consists of three-dimensional printed spherical models of the star and eight planets that make up our Solar System. Each model features a ring retainer underneath to prevent it from rolling away.\r\n\r\nThe Sun is printed in a 1:5,000,000,000 scale from its actual size, while the planets are printed in a 1:1,000,000,000 scale.\r\n\r\nTo differentiate between each model, print them in the following colors (colors in brackets should be painted manually).\r\n\r\n• Sun - Orange\r\n• Mercury - Grey\r\n• Venus - Brown\r\n• Earth - Blue (green landmarks)\r\n• Mars - Red\r\n• Jupiter - Orange (white frames)\r\n• Saturn - Yellow (orange rings)\r\n• Uranus - Dark Blue\r\n• Neptune - Purple\r\n• Retainers - Black\r\n\r\nThe following table shows the real diameter dimensions, printed diameter dimensions, and reduction scale for each model.\r\n\r\n• Sun - 1,391,016 km -> 278 mm -> 1:5,000,000,000\r\n• Mercury - 4,878 km -> 4.8 mm -> 1:1,000,000,000\r\n• Venus - 12,100 km -> 12.1 mm -> 1:1,000,000,000\r\n• Earth - 12,756 km -> 12.7 mm -> 1:1,000,000,000\r\n• Mars - 6,787 km -> 6.7 mm -> 1:1,000,000,000\r\n• Jupiter - 142,984 km -> 142.9 mm -> 1:1,000,000,000\r\n• Saturn - 120,536 km -> 120.5 mm -> 1:1,000,000,000\r\n• Uranus - 51,108 km -> 51.1 mm -> 1:1,000,000,000\r\n• Neptune - 49,538 km -> 49.5 mm -> 1:1,000,000,000\r\n\r\nIf other sizes are required, they can be recalculated using the Solar System Escalator at http://www.exploratorium.edu/ronh/solar_system/.
