A classic UFO hollow body disk designed for plastic or steel materials to reduce cost.
The central dome has a spherical hollow cavity with four open windows or portholes on top. The hollow cavity can be used to hold small objects such as paper clips. If you opt for a steel option the UFO top spherical cavity may be used as an incense burner. The bottom of the UFO has three rounded leg supports.
A version with a central bottom hole, just in case you want to mount it on something, can be found at the following
