I'm using the old motor mount "foot" along with two 2mm spacers and a M3X8mm button head screw to act as the battery standoff. Actually using two of these now because for some reason I have another "foot" leftover
Had to raise the rearward one with a 2mm spacer plus some other leftover part
(conveniently pink as well) since towards the center pulley the belt is a little higher there. Looks pretty nice... even more pink than before
