After 20 days of waiting, gears arrived.
I am pleased with smooth match with previously printed test gear sector.
Now I have to print the whole sector (110°)... and remove a bit of material from the neck of the small gear (where the hole for grab screw is now).
As the gears are modulo 0.6, I will have up-gearing ratio of 365/10 = 36.5, and with 40 ppr (and quad decoder implemented in Ek' box) I will have 5840 tics/rev which results in 3.7arcmin resolution.
