And 3D print an AR-10 receiver.

    Wow, my favorite fast food. A Mac in a Sack.

    The folks making these printed AR lowers should also print the stock as part of the lower. The recoil spring tube hole is a weak point on these.

    Kristophr, the print bed is usually too small for printing everything in place, the AR10 receiver is just about maxing out even the largest print beds.
    Warfairy has done some experiments with printing parts separately that are then glued together, there has been some success with that, but the alternative that has worked is over building the buffer tower.
    You can see in that AR10 design that some parts are way over sized, not sure what they did with the buffer tower on this one for sure, but for instance you can very easily tell that the front take down pin is a bolt due to the overly thick receiver.

    OK, I didn’t realize he was dealing with tool limitations. But I still think Cavalry Arms’s solution to the problem was the best one.

    I think Mitch Leary was ahead of the curve on this subject.

Remember, I do this to entertain me, not you.
