Mag for rubber band gun rev.03

This is inspired by this: http://www.thingiverse.com/thing:268524
I printed this gun for the kids: http://www.thingiverse.com/thing:518796
And then I thought the mag was looking pretty cool, I printed it without checking into any details. That mag does not fit this gun, it is for an older version of the same gun. So I designed my own mag to fit this rev.3 gun.

There is a boss on the mag, with the same shape as the pocket on the gun, it fits in there very nicely. So before tightening all the screws, but the mag there, and then you can tighten everything. If you want, there is also an extra screw to attach the mag more securely than just with that pocket. Just drill a hole in the barrel after you installed the mag, and use a #6 X 1/2" screw. The mag has the sliding door just like the one I got the idea from, to store your rubber bands.
