I finally received the rollers...well, TWO rollers

In German there is the word 'paar', which means some, more than 2 at least. Then there is the word 'Paar' with big P, which means 2, a pair.
I spoke to the guy who took my order and I said 'Mach mal ein
paar' (make a few) and he understood 'Mach mal ein
Paar' (make a pair), because I told him that I need those rollers in pairs

The good news is: they fit exactly

Unfortunately they didn't have the right taps (thread cutter) for the threads where the encoder wheel is mounted. So I drilled them to 4.2mm and cut a M5-thread. Used M5-screws and everything is well.
I'm not sure how many he will make now but I said make 15 pairs (30 rollers)....we will see.
I will add screws for the rollers when I get them.
Cost is 13€ for a set of two rollers.
As I said there is no hole in the roller but it wasn't a problem to fix the screw at all.
