This weekend I've been working on doing more prototype parts for the future Palatov Rev 2 D2. Rear view mirrors have been a challenge since D2 owners want to have maximum visibility on track (and on the street) which typically means a big mirror, but the mirrors we've been using have frankly been pretty terrible looking and more or less just tacked on as an afterthought. Their range of adjustability is generally poor to nonexistent being the result of bending metal tabs that attach the mirror to the roll hoop or where ever is convenient.
I think I can do better, so designing around the existing "favorite" mirror we've been using in the most recent D2's I created an enclosure that the mirrors glass can be attached to (I'm thinking adhesive foam to dampen vibration and contour around the curve of the glass). I also added a light because it seems people get really upset when basic features of every car is omitted. The total price for my mirror enclosure is less than 10 dollars (plus 8 hours of print time).
On a side note this is the largest thing I've printed thus far and the Taz 5 printed it just fine.
I think I'm onto something!
