I have converted my incubator to work in Sims 3 per a request I received form catcher1312a at TSR.
This works only as a regular crib, Sims 3 does not have the ability to have custom animated objects, so unfortunately this is all I am able to do with it.
It's found in the same area as the other cribs and the price is $275.
I was also unable to make the glass show up as actual glass as we are not able to add groups to the Sims 3 objects.
Sims 2 is so much for fun to create items for.
