Crank Boot for MTB bikes

While trying to fit my dual Wahoo Blue SC Speed and Cadence Sensor (the same apply in dual Garmin Speed & Cadence Sensor, Gsc-10) in some cases its impossible to fit the magnet on crank arm due to pedal fitting screw. So it came to me the idea to design a boot that could fit an 12x3 magnet inside and make the job.The boot is made with hard TPU (the new TPU for AMS) and i have made a slot for easy pedal pass through (without removing the pedal) and I have included small holes to pass a tie wrap as optional security. The profile is customised for accuracy and strength of the bike part.
