The least expensive option I can think of:

1: Get a 3d model of a skeleton. (One that you can edit in a free 3D modeling application like Blender, etc.)

2: Get a tape measure and a cooperative friend/significant other and measure as many of the skeletal dimensions you can without removing that pesky outer wrapping.

3: Edit the 3D model to match your measurements.

4: Print!
