About this 3D model
YOU WILL NEED A RUBBER BAND!!! How you put the rubber band on is put the band in the to cut out or slots then your ready to shoot. I added both of my designs so you could try both if one is not working. The v1 is not as good as v2 but if you whould like to inpove it you can. but make sure you tell ware you got the original design from.
