Magnetic filament detector

This is my first project that I publish that if there should be some lack or inaccuracies please forgive me.

I own a Geetech A10 printer (Bowden type) following a conversion to Direct Drive of which I am satisfied, I came across the problem of repositioning the Financial Filament sensor, not finding any solution that satisfied me I decided to build the pieces necessary.
The material you need is as follows:

1) Pair of optional female male connectors (I had them at home but you can safely pay the wires directly to the sensor).
2) A small magnet I used a 10mm x 1mm
3) A little thin electric cable
4) The reed n/o n/c sensor I took that of the link at the bottom of the page
But you can search for "magnetic reed sensor" and choose one N/C

The advantage of this system is that there is no contact between filament and sensor for which the filament is free to move in any position and there is no problem of wear of the sensor itself.
For the electrical connection, the old sensor mu
