About this 3D model

Thanks to FreeCAD anyone can adapt this thing for his individual needs. A simple case for an Arduino Uno, with included place for an LCD display (16x2 chars) and 9V battery holder, places for an encoder and On/Off swich. The USB connector is open, the external power supply of the Arduino Uno is hidden. The 9V battery holder can easily be replaced by a holder for 4xAAA batteries which might provide longer power supply for the Arduino. I'm using this case for an Intervallometer based on the Arduino Uno for my RX100M2.
