Air Pipe Toy

thingiverse

A small air pipe plays an essential role in keeping the sphere afloat; it's a suspense game to find out who lasts longer. The air pipe is easy to print - just remember to use a raft and no support with 20% infill and three shells. However, printing the sphere is challenging - try dividing it into two half-spheres for better results, then glue them together. For the spherical part, set your printer to infill at 20%, three shells, with both internal and external support, as well as a raft.
