Transom Bridge for spanning across AT-43 Shipping Container terrain pieces. Modified the original a bit; two versions one with a flat bottom and one with a ribbed/fluted version; both print fine without the need for support. The side rails are notched and will require a little superglue to hold them in place or magnetize for easier storage. Working on a collapsible model for folding the bridge flat for storage so you don't have the need for magnets... the model is included but needs some modification to work.
