Kobo Mini Spacer

the spacer can be glued(!) to the original Kobo mini to add lots of space for modding. additional batteries & GPS & Barometer for use as flight computer with XC Soar, Top Hat Soaring, etc...
it does not fit the original back cover - you will need to build a new one from a piece of epoxy ;-)

the smaller compartment easily fits for a blufly GPS vario.
a feed-through for the cables has to be cut manually - i was not sure if that was printable well.
