These setup boards are pretty useful. The pins correspond to holes in the various chassis; MR02, MR03 and PN chassis. The pins and this board also work in conjunction with the little foam car stands. The original version of this product had adjustable metal feet, this one had nothing, so I added my own stick-on rubber feet. Much better to keep the acrylic from getting scratched up, and to allow it to sit more level if there's any debris on your worktable.
