The 4th of July is done this year, but many (myself included) will be doing some more celebrating over the weekend. Besides, if not this year, there's always next ID4! This is not yet tested - I may upload a v2 later on after this weekend! Props to PrintTo3D for the flag model, which I edited slightly to put on the side. You can find that flag here: http://www.thingiverse.com/thing:10273Weight the back of the launchpad down with rocks or a sandbag, then load it up with a bottle-rocket-style sparkler and light that bad boy off!
