Honda Digital Rearview Mirror Adaptor

This is for adapting the digital rearview cameras that are common on Amazon to late 90's and early 2000's Hondas. It requires destroying the original mirror to use its articulating stalk and removing the brackets off of the digital mirror. I designed this to fit my 2003 Odyssey so I can't know for sure if it's compatible with most Honda mirrors from that era, but it seems likely. 

To remove the articulating stalk from the original mirror you must break the glass to expose the internal tilt mechanism that the stalk is connected to and use a screwdriver to pop that assembly out of the mirror shell. Next you must carefully use a heat gun to melt the plastic enough to pull out the stalk base from the tilt mechanism. It should come out cleanly with no residue but it does take some time to heat it up enough to pull it out. There is a hollow tapered bore in the base of the stalk, I found a bolt that was the right diameter (6mm?) and length to fit that hole well enough to cut threads in the bore as I tightened it. The head of the bolt has to be shallow enough to not protrude. 

Many, if not most, of the Amazon mirrors have the same or similar design but YMMV. To remove the brackets on the back of the digital mirror you have to pry away the foam pad to reveal the four screw. Remove the screws and use them to attach the adaptor. 

Any filament that can stand up to the heat and UV will do. PETG is adequate enough where I live but might warp in hot environments. I printed with 3 walls and 25% infill. Print with the flat side down and supports on because of the bore overhangs. Unfortunately the supports can be difficult to remove, I used a pick tool.
