Keyblade Accessory
When I decided to start make accessories scaled to a LEGO minifigure, the first piece I thought of making was a keyblade from the Kingdom Hearts video game series. It seemed simple enough, but it also had features that made it a slight challenge.
I included my process for making the piece in Solidworks, along with pictures of the 3D printed piece being held by a LEGO Minifigure to show it is to scale and that it fits the hand.
