Angry Bird

thingiverse

To push myself to create a unique object assembled from separate components in various colors of PLA, I began designing an angry bird from scratch in FreeCAD. Although I'm still not entirely satisfied with how the components fit together, I'm proud that I was able to design the model based solely on 2D representations from the game.

Print Settings Printer Brand: Ultimaker Printer: Ultimaker Original Rafts: No Supports: Yes Resolution: 0.2 Infill: 20% Notes: I used supports on the tail, brows, bottom, and body because I was unsure if the overhangs would be handled correctly. You can prevent using supports by placing the objects conveniently on your build plate; however, I still recommend supports for the body. The colors of PLA I used: Body: Ultimate Red Bottom: Ultimate White Beak: Ultimate Yellow Brows: Performa Black Eyes: Ultimate White Tail: Performa Black Post-Printing I glued all items together (they don't "click" together) with some two-component epoxy. How I Designed This FreeCAD & Meshmixer Operations Next to the challenge of designing an assembled object, it required creative thinking, estimating sizes and positions, and CSG operations. I primarily used sketches, pad, and revolve from the Part Design workbench to create objects. The CSG operations in the Part workbench were used to make cutouts (negative spaces if you will) for objects to fit in. The head feathers (or comb?) were most difficult. They were done by drawing basic 2D shapes in the Draft workbench and using the loft-operation in the Part workbench. Then I ended up with flat ends, but they were easily rounded off by exporting the STL, loading it into Meshmixer, and using Sculpt operations to remove sharp edges.
