Rugar SR9 +3 magazine base plate
thingiverse
this is a +3 magazine base plate for the Rugar SR9, I printed at .2 layer height and 20% infill with 4 perimeters, as long as you have a good perimeter count then the percentage doesn't matter too much. I have yet to shoot this but I have hand cycled many rounds through and it has not failed. it should fit and function with a friction fit but if you really wanna go nuts you can put a dab of super glue in the cracks to lock in for good. I recommend shooting many rounds through before you go the glue route to make sure it is fully functioning.
