Battery Buddy – Figure khớp nối cho pin AA

Give your dead AA battery a new life as a fun articulated figure!

Named by Dr Operator!

Instructions

Two 3MF files are provided with all parts. The first one is at 100% scale and fits a AA battery. The second is at 179% scale and fits a standard glue stick (should fit both the Bambu glue stick and the Kores stick that comes with Prusa Printers). 

A printable AA battery is also included if you don't have one. Try adding a filament change for the colored top!

To fit other cylindrical items, simply measure the object's diameter in mm and divide by 14, then scale all parts by that amount. For example, the glue stick is 25mm in diameter, so 25/14 = 1.79 = 179%. Scaling below 100% may be tricky.

The hands are compatible with Lucky 13 series accessories. If you're scaling up the parts, apply the same scale to the accessories.

Print settings

If you've printed any of my other jointed figures, you should be familiar with the recommended settings.

PLA is not recommended because it will “creep" over time and cause the joints to go floppy.
