This thing was made with Tinkercad.
This is a bunny test shape that I made with Tinkercad. I have NOT printed this on my 3D printer, so I do not know if it will print correctly. If and when I print it I will update this URL.
This is a redo of a previous version that didn't seem to download from thingiverse. I tested the download and it worked for me, so it should work for you.
