AA to D cell battery adapter

Print in the orientation shown/provided, without using any print supports. I recommend printing with 3 walls and 10% to 20% infill. To complete this build, you will also need an M4 x 8mm button head screw. After printing, insert the M4x8mm screw and if necessary, cleanup any remaining plastic from the breakaway bridge support; so that it does not interfere with the electrical connection to the top of your AA battery. V2 offers a bit looser fit, to accommodate Eneloop and Ikea Ladda batteries.
