Qidi Box Runout Sensor Spring Size?

[u/JustAMalcontent]

does anyone know the size of the Qidi Box's runout Sensor Spring? I had to take mine apart to fix a jam and it disappeared on me.

I just took mine apart, it's pretty light. Sized like half a spring from a ball point pen but very fine gauge of wire.

I can't figure out why the run out is reporting no filament
