Bigtoy, contact tterev3 Kids a damn genius! Easy to work with. Also I think Hoop could help with the MCPBs based on what he is doing for quad XP packages. That machined quad idea of his I think could be adopted very well to your project. Also you could toss this Idea into the Oshpark thread, there are a lot of very capable scary smart folks in that thread. With all of you working together I’m sure something amazing could be produced.
On a similar note, I just purchased a 2015 Tundra. The fog lights are wimpy. That cylindrical host you made, I think with an aspheric lens and an MTG2 would be an amazing flood light and more simple to design. If shortened and made to fit in the fog light housing of the Tundra it would be awesome and without rival.
