Geeetech A30 filament sensor support

UPDATE 9/11/2018: When I tried the case for the sensor, I made prints with very few retractions. Now that I've made one with many retractions, I saw the problem of the sensor coming out of the case. I modified the design by adding a removable rear pin, so even if you want to remove the sensor, it's easy to do without gluing or blocking it. Just insert the pin into the hole and it fits perfectly on its own. If it's difficult to enter, print the pin at 95% or 90% scale. Let me know if this works better! Finally, it happened to me too... the filament was wrapped badly and blocked! So I broke my sensor (as in the picture). You can still use it, but I preferred something more fixed that could maybe guide the wire. That's why I thought of creating a "shell" to contain the sensor! I've made several tests, and this one seems the most suitable. The sensor fits easily into place, and if you want to fix it, just use the photo I took to pass a self-tapping screw that blocks it. Remember to print it standing up, not lying down, so you won't need any print support! I recommend printing at 0.1... 0.2 mm layer height, as the lower cavity can struggle with iron supports.
