More work on the V9000 lower receiver

After I completed the first 3D print of the V9000 lower

I notice some changes that needed to be accomplished. In fact I noticed a lot of changes that needed to be made to my solid model. some of the changes are inside dimensions and some are over all dimensions. In this case on the first print the fire control housing would not fit properly into the receiver. The walls were to thin and to far apart and the length of the receiver was not correct.

The good news is that the magazine well is correct if tight.

The second print corrected a few of the items. A radius was added between the magazine housing and the side of the fire control receiver.

The internal dimensions and  wall thickness was corrected.

The hole for the magazine release was added.

With this print completed it is time to update the solid model.
