You can use battery sensors and storage sensors as tier 1 platforms :) place one on true flat, put the scrap flower onto the tier 1 slot, then pop the leveling block once and bury the sensor with that height. It will leave just the flower visible

Oh yours is at least as good as mine! You are doing some really amazing work! :)

Is this is adventure mode/survival? It's a beautiful build!

Congrats on 6 awesome years!!
