This is the result of a 3D Scan I performed using 123D Catch from Autodesk. It is of a tree stump I found while in a park.
This is a good print to use to test various angles, flat surfaces and resolution. Feel free to print at various resolutions and infill settings.
Let me know what you think and if you would like more scans uploaded!
I found 20% infill to be the best to avoid any holes in the flat areas of the stump. This print should print fine without support material.
My print was done on a Powerspec 3D Pro using ABS. Sliced in makerware.
