i have a file originally created in sketchup and exported via various formats to blender. the sketchup file is considered a "solid group" in sketchup, so is watertight and the stl file which i eventually exported from blender is also watertight and printable according to "willit3dprint" and "netfabb". the file is attached in a number of formats it wouldbe appreciated if anyone could shed some light on why it is failing to print.
please note i have no printer at home and the printing is being done by an online service, i won't name them here, the printer type is an objet connex( where support material surrounds the model and must be hosed off after printing). i have more or less no pictures of what is wrong with the prints but have been told that there was "peeling" on the wings.
the zip file contains the sketchup model, some blender versions and some stl versions.
