This will fit in the cubby in front of the cup holder of a 1999-2000 Honda Civic. It's designed for a 20x4 LCD display, and the sides are large for buttons, because I'm not sure how I want to do the switches or which switches I'm going to use. The first few pictures are of a "quick print" with little infill, no bed prep, and a little effort as possible just to get something to test in the car.
This will work with any Arduino-based thing. I'm in the midst of making a fork the BMDatalogger code with a whole bunch of tweaks/changes to make it a bit more usable for me, which may be released in the future. Marc Boulet is a crazy dude who threatened my life, my wife's life, and my daughter's life, so I will not help him in any way. I strongly suggest not to do business with him at all for any reason.
Works great with Honda Tuning Suite and eCTune!
It will fit snugly with some foam tape around it to reduce vibration and ensure a good fit.
v3 has no button holes, it's up to you to either drill them or modify the CAD.
v4 has holes for these buttons:
This screen is what it's designed around:
This bluetooth adapter fits into the right side cubby:
And you have to figure out how to mount your Arduino Nano yourself. I used the dupont cable end I cut off to make the button connectors and superglued it to the base/back.
The base is made from the source of this remixed part with no modifications, it didn't seem necessary to spend time on something that worked perfectly as-is.
