Magnetic PFTE coupler adapter for Prusa Mini filament sensor

Adapter that attaches the magnetic PFTE coupler directly to the Prusa Mini filament sensor, no more dangling PFTE tube necessary.

This also solves the problem that the filament sensor does not hold the input PFTE tube tightly at all. When attaching the adapter, put about 20mm of PFTE tube between the adapter and sensor body (as much as it fits). The adapter will lock it in there.

Attached by swapping the M3 screw for a bit longer one. You should have one in your Prusa Mini spare parts kit. Uses 5x5mm magnets.

Print with magnets facing down and some supports for the overhanging body.
