This toy was made for my son. I wanted to make an unusual gift. My search led to this project KAZKIN. This is a Rubber Band Gun.
Of the variety of guns, I chose SilverWolf-SR.

I then used MasterCAM X4 and my mill. As a result I had the parts:

After assembling and debugging the toy was ready for my son!

You can download the parts of Rubber band gun. All parts are in the format of SolidWorks2010 and STL-files..
