Jett Knife Fidget Spinner

Objective: Recreate a knife from the game Valorant that also works as a fidget spinner — a Christmas gift for a friend. Problem: When spinning, the center of mass wasn't in the center of the ball bearing, so the knife wobbled. Solution: Small tungsten cubes at each end at varying distances to balance the blade and handle. Modeled the in-game knife in Fusion 360 with a hollow cavity for a ball bearing. The blade and handle alone weren't balanced — tungsten weights inside both ends bring the center of mass to the bearing axis. Multiple iterations were needed to find the right weight placement (visible in the photos). Filling, painting, and sanding the print introduced a slight imbalance from the added material weight.
