UPDATE: There are 2 versions, the file with Revision 2 is more refined so the faceplate unit can sit lower vertically when mounted from behind, it also allows more adjustment. I left the old version in case it happens to better suit someones application. Adapts the supplied mounting bracket with a Kenwood D710G faceplate to a standard 1" ball, part #RAM-B-238 This does not require threading screws into the face-plate unit itself. You will need M4 fasteners longer than the ones supplied with the radio, and fasteners for the RAM unit.Use 100% infill for strength. Use ABS for high heat environments.
