So now that I've got an AR-15 built and I've been having fun shooting it, by tinkering side is taking over and I'm wondering what the best 3D print plans are lowers.

I tried Google searching and got way too many results to know what's good and what's not, and most reviews are a couple years old or older from when 3D printing lowers was new and all the rage, and mostly talk about how they don't last for very many shots but are getting better. (2013 seems to be a popular year for this)

Can anyone point me in the right direction?

Thanks!

Quick edit: Also interested in other gun-related 3D printing, so sources related to that would be helpful too

A lot of people have made a lot of videos on 3d printed lowers. This is my take away from those...

There are 2 weak points on 3d printed lowers. The area where the buffer tube connects and the area around the trigger and hammer pins that bear the stress of firing.

I have no idea how to solve the first problem but I figure that the second could be fixed using 2 metal side plates.

Maybe better materials would work? I dont think its viable but if you are looking to fluff up your numbers for the buyback, dont forget to register them.
 
Once one has a viable model, it can be rendered for printing or milling.

As mentioned, strength issues can also be resolved with side plates and anyone with some time and patience can modify the CAD files to incorporate flat stock which is tapped/drilled.

Similarly, casting may be learned skill but also isn't out of the reach of an enthusiast or hobbiest, nor is creating a 3-axis Arduino CNC mill controller.
