I need a quick helmet display stand, so I decided to design a simple one myself. The bottom of the display stand is hollow, and it can be filled with sand or other media to increase its weight.

There's one thing I should have considered. I ended up putting some padding above the display shelf, but it won't be visible when in use, so it doesn't really affect me.

The height of the head part is 150mm, and the bottom has different heights to choose from to accommodate helmets of different sizes.
