A multiboard holder for a pair of adjustable wrenches / spanners.  They use multiconnect screws (not mine but included for convenience; linked below).

Two sizes: “small” fits my 6" (150mm) wrenches, and “medium” fits my 8" (200mm) and 10" (250mm). Let me know if you find other sizes work, or need bigger/smaller and I'll update the models/description.

No supports needed.
