Wave FIFO Battery Holder

thingiverse

A stylish battery holder for AA or AAA batteries that is first-in first-out. This is a parameterized OpenSCAD model. You want to do AAAA or C cells, you should be able to measure the batteries and change the parameters in the model to produce a new holder suitable for your needs. You can change the amplitude of the wave and the period as well. You can make it taller if you want to store a lot of batteries, though it might get tippy if you go too high. I haven't tested all the possible parameter settings, so let me know what you find. I think that if you make the period too short the batteries may jam. Another question relates to the dovetail joints. They are tapered and on my printer, they wedge tightly with the struts slightly below the surface. What happens on your printer? Some people said they had trouble getting it together so I made some undersized struts where the dovetail is smaller. These are for the AA size holder. If you test them out let me know how they work.
