IMPORTANT UPDATES. SEE INSTRUCTIONS. 7/15/15
Spent a few hours this morning simplifying the great work done by dan0nator. This set of parts is smaller, having joined several side plates together- these will take longer to print, but the whole project is more robust and easier to put together.
I may make a system so that the hammer can be cocked and the trigger will release it in the future.
You can find a file for bullets here: [I have not printed these]
Print one of each file- the rotating piece in front of the cylinder needs to have a little bit of the right-side corner sanded off to enable smoother rotation. Almost no one can tell once painted and assembled. Ill get a photo indicating the corner uploaded soon.
-The front plate in particular should be printed with minimal support-to-print interaction.
-Let the parts cool to room temp on the printer before taking them off. My first cylinder is so warped on the bottom I cannot properly put the whole model together and have it still rotate.
-I found that the strongest way to put this together was to friction weld around the edges and then sand smooth. Alternatively, use contact cement.
Test fit all pieces before attaching anything together. The parts around the pivot block often need a little adjustment.
DO NOT Put the two larger front sections together first. You must put the center_barrel and pivot_block in between as you put them together- they will not go in afterwards!
Then connect the two large rear sections- don't forget to drop the trigger in (3mm filament or pin for correct rotation). Place cylinder on its pin and install. Install the rear half by dropping in on the back end of the cylinder pin first, then rotate the front into position under the rotation mechanism.Hammer goes where it should, using a 5mm pin/bolt. Sand the outer face of the front barrel to clean off any bumps with 80 grit. Slide the front plate on the back end of it. Set this on the front of the gun and check that everything fits. When it does, connect those two parts on as well.
-Flipped parts and re-uploaded 7/12
-Flipped front_barrel over to print without supports 7/13
-Build warning and general updates to build instructions. 7/15
