Yeah, the holes will match up with VESA hole patterns, I guess. But that's the only 100mm-based standard I can think of. I would have[1] chosen a size that matched with 2020 rails, or LEGO bricks, or Erector sets, or common lumber (1.5" is a multiple of erector set beams, so two in one if you go that route), or something. [1] have. 1/3-scale two-by-two (1.5" square lumber)-based gridbeam actually works out really nicely.
