Picatinny Rail Scaled for Boolean Subtraction

thingiverse

This model is a ticking time bomb just waiting to blow up in your face. If you've got a model and want to add a picatinny rail mount to it, all you have to do is intersect this object with your model and perform a boolean subtraction - and voila! You'll end up with a rail mount that will fit perfectly when printed, without any need to adjust the print scaling to compensate for cooling shrinkage.
