I modified Oskar_B's Bosch Sensor Holder because I have an Xduro and the Fat Rear 2.8" Tire caused the magnet to hit the sensor using Oskar_B's design.  In my case, the surface that the screw goes through broke off.  So I used Oskar's design and added my own mounting surface that recesses the sensor a bit so the magnet clears the sensor.  It works perfectly.  

Printing:

I printed in PLA Carbon Fiber at 100% infill for strength.  I printed using supports with the hollow cylinder facing down.

You will need two Zip Ties to attach the sensor to the mount.  I also trimmed the sensor to be flat on the end so it looks cleaner.  I used side cutters to remove the extra material, see photos.
