This is a Patreon 3D Model Archive release for December 2019.
These were something that we often had around the house when I was quite young and, although they are normally Christmas-themed, I tried to make these so that they would be suitable for scenes all year around.
If you're not familiar with these mobiles, they work really simply: the heat from the candles rises, causing the "vanes" of the windmill above them to turn. This, in turn, can either a) cause a wheel with ornaments or charms to spin around, or b) cause a wheel with a couple of clappers to turn and strike a pair of chimes. As long as the candles are lit, it continues to run without any other form of power. To a small child it was truly a magical thing. :)
