Revised Ball Corner Guard

Revised version of my printable Ball Corner Guard.

The corner base is now true 90°. Also the ball is more integrated into the corner and not protruding like before. ( This can be adjusted via the m parameter. )
There are two screw holes per side now. You can define an offset, so the screws won't cross. Or disable screw holes ( s = 0 ) if you choose to use glue to attach the corner guards.
