The file 'Battery Cap For Cheap Red Dots Bushnell And Simillar 3D Printer Model' is (stl) file type, size is 191.2KB.
I lost my original cap so I designed a new one,
Just put some tin/aluminum foil on the battery and contacts so it makes a connection.
If it doesn't fit try resizing it in a slicer so it fits.
