AAA to C-type battery converter

thingiverse

Basic construct for use with a AAA battery so that it can be used in a C-type battery device. Because AAAs are slightly shorter than C-cell batteries, you will need to add something metal at one end to complete the connection (I used pennies or crumpled tin foil). Two copies of the converter, one at each end of the AAA battery, are sufficient for low-motion uses, but you may need to make more bracers if the batteries are going to be shaken around a lot while in use. The gcode file prints 4 versions of the holder; the STL file has just a single version of the bracer. Each bracer uses about 0.5 g of material.
