The original script worked with the version of AOI that I am using.<BR/><BR/>To make it hollow presumably one has to subtract two as I don't see a shell command in AOI.<BR/><BR/>Looking at the dihedral angles we should be able to print the first four platonic solids with no support and the icosahedron is only 48 degrees from vertical so might just work.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-68525249603202058192008-12-01T07:00:00.000+00:002008-12-01T07:00:00.000+00:00Another way to get dodecahedrons and other platoni...Another way to get dodecahedrons and other platonic solids is to use the Platonic Solid script in Art of Illusion. The version with the current AOI doesn't work, maybe because of an API change, so I took out the crashing code and saved the updated version in the "Art of Illusion Scripts" folder in the skeinforge reprap_python_beanshell zip file.Enriquehttps://www.blogger.com/profile/09426013757234244524noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-16655148715317506052008-11-26T12:03:00.000+00:002008-11-26T12:03:00.000+00:00No I don't think anybody has tried anything yet.Ia...No I don't think anybody has tried anything yet.<BR/><BR/>Ian Adkins has suggested dipping in MEK solvent would give a smooth surface.
