Align 450 Helical Motor Pinion Gear (11T) (3.17mm)
Tarot slant pinion is cheaper and better material/quality.
Otherwise there is no issue with this pinion

slant gear has 121 tooth, so 11/121 = 11 : 1 motor-to-head ratio
normal gear has 150 tooth, that means 150 / 11 = 13.63 straight tooth pinion equivalent.)
