Fuji NP-W126(S) battery clip with charge indicator

thingiverse

This is a battery clip for the Fuji NP-W126 / NP-W126S rechargeable batteries. I found the little plastic bags that come with the batteries rather annoying to use, so I wanted a quick clip solution which would protect the contacts of the battery from dirt and also prevent accidental short-circuiting. I added two cutout triangles which can serve as indicator whether the battery is charged or flat. If the red dot is at the triangle pointing up the battery is charged, if it is at the triangle pointing down it needs to be recharged. The battery is held by some springy clips and shouldn't fall out as opposed to friction based designs which would eventually wear out.
