The Ender 3 and the A10/M have different wheel spacing. Lot of the Dual z brackets bolt up to the adjustment wheel and this one uses the little bolt next to it. Depends on the wheels you have like dual bearings or single, you may have to adjust how long the spacers are.

You will need the following hardware to mount

(2) M5 X 35 Cap Head Screws (I used longer, it's what i had)
(1) M4 X 50 Cap Head Screw

I would of remixed this one but i lost the STL and they removed the main bracket. i like this one better because the 8mm rod nut has more adjustment.
I used the spacers from the link below.
