About this 3D model

Pirate3D Design Competition Blakely 500 lb cannon found in Real Felipe Fort in Callao, Peru, named "People´s cannon" because the people of Callao armed it in a full day and night. The design doesn't include rails and was made with a rough draft, not a blueprint, so I had to take some licenses and compare it to real pictures. This is my first work for a 3D printer, I hope you find it interesting. Please read the instructions on How To.
