Here is a mount for the hex wall mounting system. I created these to work with my 10 pc build plate rack. I made the spacing to allow mounts on all 4 corners of my rack to align with the spacing of the hex plate holes, although you can just use 2 mounts on the top of the rack to “hang” it from the hex wall. Files are labeled for what spots they mount on the rack. You'll need to print 2 sets of the 3mf file to have all four corner mounts. Uses 3mm x 14mm socket head cap screws to assemble, just like the rack. Link to the hex system below.
