Hummingbird Battery Base
thingiverse
I designed a battery holder sub-base using Autodesk Fusion 360 because the original model didn't have a place to put the motor's power source. The new sub-base allows the original base to slide right in. Leave the power wire long enough so you can remove the base from the sub-base to change the batteries. Tuck the extra wire back into the sub-base when it's closed up again. You'll also need a small toggle switch and a 4-cell AA battery holder - I used Jameco #105858: https://www.jameco.com/z/BAT-HOLDER-R-4x-AA-Battery-Holder-with-6-Wired-4P-Connector_105858.html Attach the battery holder to the sub-base with hot glue, or you can just leave it loose.
