9 volt (PP3) battery holder with contacts

thingiverse

This is a holder for PP3, 9-volt batteries, with built-in contacts and no need for support during printing. Print two parts and cut two strips of brass, measuring 35 x 5 x 0.127mm (or 0.005 inches thick). Bend the strips through the holder's holes to connect your wires securely. The battery will only fit one way, so ensure you get the polarity right to avoid any problems. A Parasolid CAD file is available for download in the downloads section. Rotate the main part before printing to print it without support.
