I’ve nearly outgrown my 3U84 eurorack, so have broken ground on its replacement: a 7U84, using the original skiff’s Vector rails for some 1U utilities, and four secondhand z-rails from a friendly lines-ite as the primary racks.
From CAD:

to my dining table:
and though I designed it as a swoopy tabletop case, I made sure it’d balance vertically too:
The 1U rails are currently in use and thus yet to be added.
Won’t have time to populate it and finish the fit-out til after this project is done, but I’m pretty pleased with the conceit.
(of course, it means I also now have CAD files for Vector and Z-Rails should anybody need them).
