This is the design for the reflective and focusing mirror for the DAV5 V2, the mirror's are 25mm in dia. and 2.2mm in thickness, all parts will be 3-D printed for this project. The prototype as it stands right now, has a cost of $293.81 US, all tolerances as far as the designs go are 0.05mm +-, so I will have to see what the actual results turn out to be when the final parts are produced and make adjustments from there.
