LED backpanel for MCR USB card reader
thingiverse
Since the MCR USB card reader only has boring little green/red LEDs, I designed a much better RGB LED backpanel for it. It requires 10 LEDs / 16cm of a regular WS2812B/SK6812/neopixel LED strip with 60 LEDs/m. Prints best with 0.5mm extrusion width. The holes of the alignment and mounting pins may be tapped with M4 threads to fix the backlight module in place with two 10mm M4 screws. The optional cable box with screw terminals is just glued in place. Requires matt, frosted, milky, natural filament. Printed with Reprapper natural PLA (bought 2013)
