Comgrow T500 - Filament Sensor Saver

The Comgrow T500 is equiped with a low-cost chinese filament sensor which can be quickly damaged even with non abrasive filament, so I've created a simple bracket to be able to use a PTFE tube to protect it.

You can use the original screws provided with the printer and the only thing you need is a small piece of PTFE tube OD 4 mm, it's better to use ID 3 mm or at least 2 mm to avoid jams when unloading filament (Capricorn tube is not recommended)
