Canon for RPG sailing ship

Low poly model of a swivel gun for the Sea Ghost tabletop RPG sailing ship (and its derivatives). As well as a slightly higher poly model depending upon how much detail you both want, and your printer can do. I did not add a hole for the cannon and the mount attachment point due to the small size of this model. My plan is to print it at 60% to 80% infill and drill the hole sized for a pin, or tiny tiny nail. The bracket size is to the width of the Center rail section of http://www.thingiverse.com/thing:1078333 or http://www.thingiverse.com/thing:1431553
