Concertina v0.7.0 assembly, central wires
A stage in the assembly of a Concertina v0.7.0. Here, the right-hand bookend subassembly has been prepared as shown here, then attached to the central housing with screws at the assortment-drawer seam, and then the bundled wires originating in the left-hand side (shown here) have been routed through the left-hand bookend (also attached to the central housing as shown here)), and through the loft of the central housing, to poke into the right-hand bookend.
