This maple tree was modeled in Arbaro and imported it into Blender. I based it on the maple tree in my backyard. I intend to make a more interesting scene to put this into, and I need to fix the base of the trunk, it looks horrible.
I needed a new shelf to house my computer equipment and fileserver in the basement. So, I modeled it in Blender for scale, and purchased materials based off the quantities used. The final product looks and functions just like my model.
