An old file from my Pepakura making that I discovered in Pepakura Designer you can export to . OBJ and in "Windows 10 3DBuilder or 123Design" export to . STL. I don't have the skills yet to improve further on the model, but maybe someone out there want to tidy up it. If you do take some time to clean it 17, please upload it back as a remix.
Please note this was uploaded to the internet as a free down load. So I cant take credit for whom really made the file.
