New release mechanism for magazine

So here's a cutaway view of my latest grip model.  There's a nice amount of material so that the magazine will not bind inside of the grip.  The magazine now has a bar with a notch in it that will hopefully catch on the to-be-designed release button.  I haven't decided how to approach the spring loading for the magazine, but it will come to me once I have the release mechanism designed.

I'm starting to think that I am going to have to go all-SMD for the PCB because there really isn't a lot of room in there!

Yet another grip design

On this iteration, I went away from designing the grip as two separate pieces in favor of printing one piece.  The advantage here is that I can easily mirror features from one side to the other, as well as get a good feel for the grip without having to join two pieces.

I added traction features to the sides and front of the grip.  I also enlarged the bosses that go between the fingers.  The grip needs to be more comfortable so I increased the radius of curvature all the way around.  The rear curvature needs to change more so it's more like the Glock 17.

Next I will add the hole in the bottom for the battery magazine, and try to come up  with an eject mechanism and way to add a custom spring.
