A few finishing touches:
1. Make a vertical cut to the back of the 'L', right of the base - this means the arm for the wheel magnet can actually be used. Handy 
2. The back of the 'L', left has had a section removed from the bottom. This allows room for the cable tie required to hold the sensor in place. Although as I said earlier, it's probably best to remove this whole piece to be honest.
3. At the extreme left/right make two cuts and small fold in the horizontal part of the mount. These should be measured against the frame - they 'grip' the brake cable routing mounts which stops the whole thing shifting up and down the swingarm.
4. Round off all the sharp corners and stuff of course.
