"The word is Plastics" Part 4

3D printing has become my friend, draw the part, print the part and review the part before you make one from steel. What is not to like?

From idea, too CAD, to plastic, to concept fruition.

Of course none of these parts could be used to build a functional firearm but the 3D printed parts do offer you a visual model to tweak a design concept or abandon it.
