The Roto Damper was never uploaded to git hub so you could download the print files and have someone print you one. You can get the Adapt-A-Damper print files off the web and then find a printer to print device. I would go that route. Heatermeter is still the best solution for ceramic cookers imo. Still use mine for long cooks and have been very happy. Only time I don`t use mine is when I cook burgers. Be careful when purchasing the servo required for any of the dampers. There are lots of crapping clones out there.
