The conch is a sacred symbol in Hinduism and is sometimes used to hold water for offering, or displayed on a stand. This is a simple stand for three sizes of conch and can be used for either purpose (with the opening down or the opening up).

This is a similar design to the basic brass conch stands widely used in India, but I believe the four-legged design provides a bit more stability especially for very large conches.

Printed in PLA. Note that it's printed upside-down (with the legs up). No supports needed. FreeCAD source included.
