Pic of finished model: BB-8 and R2D2
Download Files: bb-8 files
Update 1: A Youtuber by the name of Yoshiny Yo made a "how to" video. Go check it out: youtu.be/Vwb0Tlw4wOY
Update 2: Revell-Fan has made a version with updated texture which can be downloaded here: download
There is another version with better detail made by Revel that you can download (link in the description. For that one you will need to make a Zealot account, but the download still works there as well.
Unfortunately these are not image files (png, jpg, gif...). It is a zip file containing a pdf and pdo file. DeviantArt is not very friendly with hosting non-image files so options are a little limited. Eventually I plan to host all the files on my own website, but that is still in the works.
Sorry I can't be more help. Hope you can get the download to work.
2. Select: File > Print
3. Under "Page Sizing & Handling" select "Poster"
4. Set "Tile Scale" to 463% (life size)
Warning: Doing this will make the texture and details very blurry. I'd recommend using the same process on my other bb8 model, setting tile scale to 273% for life size.
