This part must print in the given orientation, vertically; or you'll have to use internal supports. I recommend using mouse ears on the corners.

It can be attached to a tile with two or four Panel to Tile, Multigrid T-Bolts or Snap-to-Snaps, or it can be mounted directly to a wall. There must be 6 MU/150mm/6in of clear space above this mount in order to fit a battery. If you're going to mount 12Ah batteries; I recommend using two directional snap-to-snaps on the top corner octagons, two standard snap-to-snaps on the bottom corner octagons, and two panel-to-tile t-bolts on the top row of small thread holes.
