Helmet Stand/ Display stand

This is a quick helmet rack that I made for my dad's old fire helmet. the base and the top rest are 3d printed, while the middle riser is 1 inch (.920) OD electrical conduit. this allows for a greater variability in different helmet sizes. the conduit tubing is just a interference fit, I installed mine with a hammer. I also use this same model with a slightly shorter section of conduit rise in order to hold motorcycle helmets. thanks!
