I've seen various sword holders and downloaded some. This is my holder, it's designed to display the sword without a scabbard, blade pointed down and the top piece has a pin that actually locks in place to prevent the sword from falling out. Taken steps to make sure that accidents are minimized and risk of injury is minimized.
Thank you to a user going by the name lets_try_this on thingiverse for the suggestions, I have modified this design to make it stronger and safer based upon that users input.
