Pencil Slingshot for some fun in classes or in the office.
Models are standing, just rotate to lay it flat. (I didn't print it standing)
V1 prints on the edges of the hexagon. I printed it with raft to get the necessary friction
V2 prints on the flat surface and is easier to print. I also printed it with raft to gain extra friction with higher printing speeds.
To use it you need an ordinary rubber band and something to shoot.
Have Fun.
