The file 'AA To C Battery Adapter 3D Printer Model' is (stl) file type, size is 873.7KB.
Yet again the search engine of Thingiverse failed me and no AA to C adapter design came up. So I designed mine. Now the search engine works and some very good designs are now visible to me... After design, iterations and a few prints were made... Eh, at least I confirmed my design works just fine and is really rigid radially and longitudinally
Fitting to batteries is made at the extremities, the splitting lines allowing expansion a bit. Designed with minimizing plastic usage in mind.
Enjoy!
P.S. Some sanding of the internal extremities may be needed depending on your printer settings / accuracy
