This adapter allows AA size batteries to be used in place of C batteries. This Type 2 version is for use when the battery holder requires a cylindrical battery of approximately C size. For cylindrical battery holders I recommend using the Type 1 adapter which is much faster and cheaper to print.
This is also an interesting example of how to generate a desired shape using a solid model with vase mode.
This must be printed in VASE MODE with ZERO BOTTOM LAYERS. I recommend using the 0.3mm draft mode.
Or just use the provided gcode or 3mf files.
