I mean, all are on wedges, and wedges ceilings and wedges foundations. And they’re in air, not on the ground (picture perspective).
I build mostly with t3 if for the good, this was just as test for you. But sure, my days are endless, i’ll make you a set-up with reinforced stones. Who knows ?
Wedges are tricky, and has still been. Also i use them mostly only for cosmetic purpose. I don’t relate on them for holding precious stuff (no chest filled with goodies) placed on them. I learned it also the hard way, so i avoid using them in certain ways. Not perfect, but mostly working for me.
