My initial Shapeways printed order did not return four small connecting units but they made up for it by reprinting the order and the connectors. So this enabled me to assemble these four parts (one of one part and three copies of another single type of part). The connectors fit OK but too loosely. Anyway I have already sent in a modified design of these parts as it was clear the tinsel strength would allow it to be half as thick and with considerably larger open center spaces.
