This is a simple yet effective mud protector for Bafang gearshift sensor.
No need to dismantle the the gearshift wire to mount protection: simple let the wire pass through the little gap on the bottom and push it gently agaist the sensor.
Held it in place by two plastic ties 2mm wide.
You can print it orizzontally or vertically.
