I'm in the process of building a 3D printed replica of the Battlestar GALACTICA or BSG Season 01 Blaster and I have run into a bit of a snag with movement of the trigger. The creator of the STL files made the trigger movable but didn't think of adding a means to have it be forced back into a pre-pulled state after it was released. Frankly there really isn"t enough space in the print to add a spring or springs that I can currently imagine and hence my thought is to come here for some ideas. Below are pictures of what I'm working with. Any comments or suggestions would be greatly appreciated.
