This is a basic Point of Balance stand for displaying a sword. Please note that this will only work on properly balanced swords.
This is a modification of Avioza's Mordern Pillar:
Print with 20% infill. Scale to proportions to the sword you want to display/blade thickness. Be default this stand will fit most swords/blade widths, and is tall enough to properly display most swords with medium crossguards.
I suggest gluing a piece of no-slip material to the bottom, and some soft felt on the inside.You can also paint with stoneware pattern spray paint.
