My dreams have come true. It is now possible to use a desktop 3D printer to print an AR-15 magazine, floorplate, follower and spring!
The 3D models have been opensource, so anyone can use them, modify them and distribute them. All you need a MakerBot desktop 3D printer. The latest MakerBot is sold in kit form for $1,299.
An AR-15 lower receiver 3D printer model has also been published, although nobody has published photos of the end result.
Do any TFB readers have a MakerBot or similar printer?
