Inspired by the iconic weaponry in the godfather, I modeled and printed one of the prop Tommy guns based on set and movie images.
there are three interactable aspects of the design.
the trigger sits on a pivot and is tensioned by a rubber band allowing for a movable realistic trigger mechanism.
the reload bolt is movable and can be snapped back through a rail and anchor system.
The drum magazine is removable and can be clicked in to allow for fast movement with the prop.
*Note: below is a link to a video that showcases the painting and operation of the mechanical pieces. sadly the assembly footage was corrupted. If this model gets enough support I will post a video showcasing the assembly process as well as some basic weathering.
3D PRINTING SETTINGS
The print settings vary from piece to piece. I personally printed the models using PLA however ABS would be recommended for those wanting a toy that can be thrown around and not break.
Despite using Pla I had mo issues with the strength of the print but rather had issues with the glue I used to assemble the model.
I would recommend printing smaller pieces at a high resolution and medium infill to ensure strength.
For larger pieces using a lowered resolution and low infill is very effective for high quality and high-speed prints.
*Note: the parts are high tolerances. For printers that cannot meet high tolerances, manual sanding will be needed to make pieces fit together.
