Objective

Make something big.

Design

Initial design in blender, parts in solidworks.
I designed a cat tree in blender and then make the parts in SolidWorks.

I then imported the Solidworks Drawing into CorelDraw and checked whethere there was a 2" boarder and a margin of a least 1.5" between each part.

Milling

I used the shopbot and a 4x8' sheet of OBS.
Assembly: simple screws and some white paint on the rough side of the OBS.
