To make it complete a bit of aluminium foil is necessary to connect the the battery with the pad as well as a screw of the right size. I've uploaded the openscad file if you want to modify the design to accomodate a screw with different dimensions than the one I used
I printed using ABS with a 0.4mm nozzle. The design includes some built in supports that need to be cut away in post processing, no other supports should be necessary.
