It’s a good system. There are an insane number of tool holders already available for download, and it’s pretty easy to design your own by sticking the existing male hexagon part onto a model in fusion 360. Note the direction of the hexagons when mounting the panels… I had these rotated 90 degrees at first without realizing, which means all of my tool holders would have been at the wrong angle lol. Had to patch some holes and remount the panels, ugh.
