Hubsan Battery Tray with Charge Status Dividers

A battery tray that holds 240mAh Hubsan batteries (for the Hubsan X4) with movable dividers to indicate which batteries are charged and which are not.

Print a green divider and point the arrow towards the charged batteries, print a red divider and point the arrow towards the spent batteries. As you use your batteries, move the dividers and batteries.

Parameters in the OpenSCAD source should allow it to be easily customised for the bigger Hubsan batteries if you want to try - just change
