Minimal bracket for the G1W dash cam that snaps on to a gentex 313 mirror. Uses lower half of original suction cup mount that comes with the camera. Camera is completely hidden behind the mirror and does not block the light sensor for the auto dimming mirror.printed with supports and 30% infill on a da vinci 1.0 depending on how big of a gap you have between your mirror and your windshield you may need to shave off a very small amount of plastic to get a secure fit. also, note that adjusting the mirror mounting screw will change the gap. may work with other gentex auto-dimming mirrors, let me know if you try it with any others in the comments.
