I couldn't fit the original object on my print bed without printing it vertically or at an angle, which gave it no real strength. I just trimmed the edges off in Fusion 360 to fit my print bed (which claims 200mm max, but will work at this size of 208.4mm barely).

I printed at 101% scale so the tile would fit right. The 6" tiles I bought at Home Depot aren't completely flat on the sides (they have these notches outward).

Hope this slightly trimmed version helps someone else fit it on their printer bed!
