STL Files are now able to be added and viewed on forum and blog posts as well as robot project posts.
Attach .stl files using the file attachment panel.
The uploads have a maximum of 4Mb and your stl should be created so it is centered on x and y and the bottom on the z axis to be displayed properly in the viewer.
You may upload more than one file at a time and the objects will be selectable via a drop down.
Let me know if you guys have any issues :)
