After seeing Joerg’s legolas designs I decided to design a legolas myself. The kinds of bow Joerg designed around are expensive in my country so I found the cheapest bow I could afford and built a legolas magazine for it. That worked really well and the design is a success I'm my opinion. The bow I use is a Man Kung Cb30. Here is a picture of that design: Once I had completed that design I really wanted to get away from having to buy a bow. So I started to design a 3d printable compound bow for my legolas mag. My complete bow and legolas magazine can be made cheaper than the cheapest compound bow I can buy in my country. Here is a picture of that design: The bow uses pvc electrical conduit for limbs and aluminium tube for the barrel. It is meant to be a self defence weapon for people who can't own a gun or don't want to own a gun. The bolts weigh 270 grain. I am comfortable that a gut shot from this, with a broadhead will take the fight out of most men. The barrel is replaceable so the bow can be used as a compound bow with standard arrows too (although I have not tried this) . The bow can be fired vertically or horizontally as is the user's preference. There are 3 cam profiles on each cam. One profile is for the bolt sting, another for the cam syncing and yet another for latex tubes which offer additional energy to the bow. If you have questions I will be happy to answer them if possible.
