Toy Artillery Mortar

_______________________________________________

About:

Pull back the spring, set the spring in the hair trigger slot, drop in the projectile and it launches automatically like a real artillery mortar. Enjoy.

CHALLENGE: Try designing a better spring or projectile? Tell us about it in the comments with a link to the upload and we will test it out. If it works better we will recommend it. Projectile needs to fly without tumbling [launched into a head wind or in still conditions].

Steps To Assemble:

1. Insert pin through the top hole on the side with the circular hole.
2. Then insert pin through square hole in the spring
3. Rotate the spring so it is in the orientation in the 3rd picture
4. Push pin through the square hole on the opposite side of the circular hole to set it
5. Push pin end on pin to keep it in place
6. Break out the thin support at trigger location by pushing it in.  This will make a nice square edge for the hair trigger
7. Pull the spring and place it in the edge of the trigger slot
8. Drop in the projectile
9. Projectile will dislodge the spring, causing it to launch
10. Projectiles are somewhat delicate and best fired to land in the grass
11. To fly best, the projectile should be printed with 100 percent infill
