The file 'Button Cell / Battery Adapter – Use A Small One For A Big One 3D Printer Model' is (scad,stl) file type, size is 3.3KB.
This thing lets you design an adapter to exchange different kind of batteries!
The STL here is for an A13 zinc/air battery in place of a LR44 (or SR44), because it happened I had these around, otherwise useless to me.
Make sure that the voltages are compatible though! (here I have 1.44 volts instead of 1.55: lower is safe but may not work properly)
