The file 'Taurus G3 Magazine Base Extension 3D Printer Model' is (stl) file type, size is 509.0KB.
These are designed to be used on the Taurus 15 round magazine. They might fit other sizes but I have not tried them. If you find that they fit another mag, please let us know in the comments. The photos show my G3 with the 15 round magazine and 4 round extension installed.
The ones named MagBase add capacity and they need the Cap to hold it onto the magazine.
The Base Cap is made to be held on with one M2 countersunk screw 5mm - 10mm in length.
The one with indents is made to match the contour of the grip but may weaken it some overall.
The ones named Pinky Extension do not hold additional rounds and do not need the Cap. They are held in place the same way as the original mag base.
I have had good results using ABS and printing them in the same orientation as they are in the stl files.
A longer mag spring may be necessary for the +3 or +4 version, but the +2 version does well using the spring from the 15 round mag.
