Team Associated have added new 3D printed option parts for the CR12 to their Shapeways 3D Printing store. First up is the battery box. It allows the use of Shorty-style battery pack for longer run time and adds additional options for adjustments to weight bias. Next up is the servo mount. This rearward-positioned servo mount improves steering geometry through suspension articulation. No additional hardware is needed to use both option parts but they require a modification of stock aluminum electronics tray.
