Filament sensor rod

I made this one for my Voxelab Aquila. It should work in Ender-3 as well, I guess.

You need a couple of M3 x 20mm bolt and nut .
I purchased very cheap Filament detect sensor in AliExpress.
This is the mounting rod for that sensor parts.
Voxelab Aquila has a connector for sensor parts but the pin assign of this parts is opposite.
I had to swap the white line and red line. ( black line is common ground ).

I am using my Aquila with direct extruder unit so i make the spool holder 90 degree by another parts. https://www.thingiverse.com/thing:5305150
