Rebuilt the WH-R8170-C36-TL front wheel as a rear wheel (3 / up to 4 spokes)

Another day with wheels (and so on).

That's the 3rd spoke.
I was thinking I'd lace the last couple of spokes all at once,
but in the end I only managed to lace one,
and didn't even have time to disassemble the 4th front wheel.
