I used to have an Omega mounted directly to a countertop, and a cutout ares with sliding shelf below(6in increments)for really huge prints. Not necessary with the 45mx, as the head will go horizontal. Its easier to print on a vertical easle set at any distance you want(check out AA's DR.), All you need is a wall projection bracket to hold the head steady.
