BLUErBOT 3d prints a .25 caliber Derringer Prototype

This prototype is just that. The BLUErBOT 3d printed this device in order to see how a shell can me made, which allows for added steel components. In the end, this device allows for smoothbore steel barrels, a steel backplate, steel firing pins, and two rare earth magnets which would render it detectable as a firearm, and legal. The device was melted down in acetone after it was printed, and was far from a completed device at any stage in its development, prototyping, or post printing.
