This is a mashup of the "2032 button cell holder" by sphynx on Thingiverse and the "Fractal" community shape script by Petr Broz on Tinkercad. IMPORTANT: You must print the two pieces separately, using your slicer to get the tall fractal part to print as a one-layer shell with base but no roof. Details for how to do this with MakerWare are at the link below. http://makerhome.blogspot.com
