Description

PDF

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.

 

2023-07-13:  Added V2 which offers a bit looser fit, to accommodate Eneloop and Ikea Ladda batteries.
