Progress continues! Alex has made the all-important color choices and N has successfully printed the forearm cup retainer, palm, and fingers. The only people who are not doing their assigned tasks effectively are Bill and me. Who knew that making molds and casts that bear some resemblance to Alex's arm could be so tricky?! Ah well. We're getting an education in alginates and plaster in the process .... Does this arm look awesome, or what?
