This is a wall mount designed for xenonjibei's decayed Master Sword model from The Legend of Zelda: Tears of the Kingdom.

Its printed without supports at 0.2mm resolution with Ironing enabled on an Ender 3.

I have incorporated holes for two 3.5mm x 30mm screws to strengthen the support arms, which I recommend using.
