Simple mount for attaching a MaxBotix MaxSonar sonar unit to a servo (or really anything else).I mount this on a standard servo arm, or you can mount it on a flat surface. It has two screw holes that are intentionally a bit small so you can drill them out for a clean hole fitting an M3 or #4 screw.I have included the OpenSCAD file so you can tweak it as needed, move the screw holes, etc.
