Geeetech Filament Detector Replacement Part

As the printer came new, I didn't even use the filament detector, because it seemed not to be helpful in making the way for filament moving more difficult. After a while I bought some test filament (wood, copper, elastic,...) and there was need for some detection of filament running out, so I tried the detector and soon it got broke.

I redesigned it and printed the replacement part, which works well. The broken ring is more stable than the original one. By chance it got white (original is black) but works :-)

And it was one of my first projects in FreeCAD
