Insted of using plastic materials in the original +bow, I used foam sheets.

Each layer is reinforced with double sheets. The three templates you need from the original write-up are the trigger template, the template with the + on it, and the barrel template. Print out two of each. Glue them onto the foam sheet and cut them out. Then make as many as you need to make it strong.
Here is a picture of the gun.


it does have a trigger, here is a picture of it primed.

The handle is filled with foam insulation.

It has a standard clothespin trigger.

This is a picture of the L.I.D. Barrel. The plans have varied since the last L.I.D. The barrel is longer than before to support the length of the templates.
I plan on leaving this white because I have already named it White Lightning
