Here are the instructions for my singleshot slingshot.

Video: https://www.instructables.com/id/Dash-Knex-Slinghot/

Step 1: Layer 1

1: Make this.
2-3: Add grey/black and blue rods.

Step 2: Layer 2

Add the second layer. I recommend connecting all the connectors to the rods and then adding in the rods. It will make it much easier.

Step 3: Layer 3

Add all the parts to the third layer.

Step 4: Layer 4

Add the 4th Layer. Make sure you add the trigger guard and the green rods in the handle.

Step 5: Layer 5

Add the 5th layer.

Step 6: Trigger and Bands

1: Make this.
2: Attach it here.
3: Add this white rod here.
4: Make these.
5: Attach them to the other thing you made.
6: Make this.
7: Add it to the rest of the trigger
8: Make this.
9: Add it like in the picture.
10: Add a rubber band here.
11: Add a rubber band here.
12: Add this rubber band to the trigger part inside the gun (I used a toothpick and wrapped the rubber band around it to get it through the gun).

Step 7: Bow

1: Add 9 orange connectors to each side.
2: Add one blue spacer to each side of each grey/black rod.
3: Add your rubber bands. The bottom rubber bands are to make the bow bend less but they don't actually work so you can leave them off.
4: Add two more orange connectors to each side of the bow.
