About this 3D model
We bought a "Wimmer Ferguson Stim-Mobile" for my newborn son, but unfortunately it only comes with a mount for a slatted crib, and my son is in a cosleeper without slats. This adapter fits over the side of the cosleeper, and the pin fits exactly into the arm of the mobile. Problem solved! This was made in [123D Design Online from Autodesk](http://www.123dapp.com/design), a really slick and easy to use tool. My wife appreciates the ability to round off edges (fillet), it makes objects so much more "baby friendly".
