I create a Adapter for the MiniDisc Player that require the LIB-902 Batterie.
Because the Batterie is new not to buy i create a Adapter for the 3,6V UltraFire 10440 Batterie in AAA Form.
Other Batteries in AAA Should be work.
The Ultrafire comes in the middle Hole and in the 2 holes comes a Metal Bolt with 4mm diameter.
Createt with CorelCAD 2016.
Print with 10-20% infill.
i made a second Version with a angle at the + end to get it better in the batterie port
i change the modell because the Trustfire 10440 is longer then a normal AAA batterie.
the hole is 47.5mm long for the batterie.
second version is no longer needed
