Remix of ffleurey's excellent AA battery holder. Uses springs/tabs shown in photo, about £1 for ten pairs on ebay.
66mm model is designed for Samsung ICR18650-26F (pink flat top) and unprotected GTL red Li-Ion's. Its more parameterised than the original and has some code tidying and the solder tab meets the wire channel now, also removed +/- text from the bottom which didn't slice/print on the original. A bit wider too. Test printed and they are pretty tight length-wise, might need to make it longer when I get the battery contacts in the post.
69mm model fits Soshine LiFePo4 black and Panasonic/Sanyo NCR18650A green/red li-ions but doesn't have as many optimisations as the above, so if you want to edit one, use the 66mm.
Unfortunately the battery springs/plates I received from ebay are 19x12 not 14.5x9 so i had to modify the design for my latest project - see the wood-colour photo with the pink battery and the 3 green boxes, and battery_box_bigcontacts.*, it also has no screw tabs and a wider wire channel as I wanted both wires to come out of the same side. Removed the polarity markings as they didn't print well.
