Perhaps you have a Spirit Halloween Jumping Spider it may have broken eventually like mine did

Here is a part to try to fix it.

I and going to stake mine to the ground via the large holes you might want to glue it to the original case, or use the holes to screw it together Watch for internal bits before using the holes to screw it together your might have electronic parts in places mine doesn't

I printed with 5 walls so the box is solid, and a 25% gyroid fill so it's strong
