Lego Arrow

The arrow consists of a shaft and head. The shaft has a Lego axle at the tip so that you can attach custom arrowheads.
The shaft should be printed from a solid material such as PLA with a layer hight of 0.1 mm. 
The head should be printed from a flexible material such as TPU. A layer hight of 0.2 mm is sufficient here.
Both parts can be printed without support material.
