Simple Parameterized round turret

Experimenting in openscad to make a simple turret for miniature gaming. It is very plain, but I think it is a good basic start for a little bit of greeby application and some paint.

Parameter variables are hopefully pretty self-explanatory. There are 3 major sections: The barrel, the turret itself, and a base for the turret to sit on.

//barrel
$barrel_length is length of the barrel from x=0 and going in X direction
$barrel_diameter_base is diameter of barrel at x=0
$barrel_diameter_m
