this is actually the thing why i'm here... making 3D Objekts real is awesome :)inspired by the work of these great ideas: http://www.thingiverse.com/thing:1272 by jrombousky http://www.thingiverse.com/thing:1416 by aylr i used Blender to model that thing as a polymesh and made some changes... it's more editable now...it's ready to print... simply generate the gcode if you like to change the Mesh in Blender, download the *.blend file or go to File > Import > STL how to export STL files in Blender? http://www.thingiverse.com/thing:4914this imported STL is again a triangle mesh... but still easy to edit...you can change a trianglemesh to a Polymesh in Blender: select the object > Tab (to switch in editmode) > A(select all) then press alt+J to convert the trianglemesh to a polymesh. use ctrl+T vice versa
