AK Stanag mag converter

During the summer of 2012 I designed a magazine converter for AK AEGs to allow them to accept M4 magazines. I sent it to my university's 3d printer to get a prototype made, and so far I am very pleased with the results! Almost all the tolerances are perfect. A second print, and it will be perfect.

Here you can see how the internals work. The M4 mags feed BBs from the front, and AKs feed them from the center. A curved tube allows the BBs to feed from the M4 magazine to the hopup. A cool little trick in solidworks is called "Shelling". You can take solid items, and create cavities within them. This comes in handy for saving weight, or saving material. In this case, I had to pay ~$12 per cubic inch of plastic. Shelling helped me cut the price of this part in half.
 When I found out I could add trademarks, I was incredibly tickled.
 Here the beginnings of the mag catch are visible. The ridges here are far too small, and the hole was removed before I printed the part.
Here's one of the earlier pictures of the solidworks file.
 This is a picture of the bath the printed parts are placed in after they are printed. Each part is printed out of two plastics. The first plastic is the actual composition of your part. In this case, it's ABS plastic - The same stuff Lego are made of. The second type of plastic is a structural support, brown in color. The structural supports are dissolved after the part is immersed in this machine for a few hours. During those few hours, the bath becomes very basic, and is heated.
 My part was placed in this little metal box to allow the studio attendant to place and retrieve parts without getting the solution on their skin.
This picture is the birth of my magwell converter, still wet from the bath. It is so exciting to see your work come to life. Nikola Tesla has a wonderful quote to describe it:
I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success . . . Such emotions make a man forget food, sleep, friends, love, everything - Nikola Tesla

Thanks for reading. I hope I have inspired a few of you to get something printed. Check your local university, or online.
