Double AA-Battery to D-Battery Adapter
thingiverse
This thing is designed to be used in conjunction with 2 AA rechargeable batteries. In this configuration the "D-battery" puts out 2.4V, which together with 3 other AA- to D-Battery adapters like [Thing 107924](https://www.thingiverse.com/thing:107924) result in the 6V normally needed for some Nerf guns. In the rendered images bend metal parts are visible. These parts need to be made out of a ~4mm wide metal strip. Such metal strips are not that easy to find. In Germany these are usually included in file organizers like [Flexi Filing Strip](https://www.durable-uk.com/filing-and-organisation/files-and-folders/special-files-and-filing-accessories/flexi-filing-strip-fasteners.html). From there these can easily be extracted, cut and bend into shape. Be aware of some isolating surface coating on these, since they need to be conductive.
