Recently i learned that GT2 pulleys are tricky in my case.
I need to get a pulley that is 40teeth/10mm wide belt/8mm bore. And i cant, for the life of me, find one.
It is either gonna be 6mm wide belt or 5mm bore... Starting to pull my hair out (whats left of it anyway).
I dont know anyone with a small lathe to bore it out, no point going back to 6mm belts as machine is supposed to be fast (not a 3d printer, that crawl.).

Its a "pick 2" triangle situation. Gah.

Thanks for the drawing, btw, thats all i needed - an approximation.
Since shaft center runs about 35mm above "floor" i can stick in whatever doesnt exceed 55-60mm in diameter.
