LED backpanel for MCR USB card reader

thingiverse

I designed a custom RGB LED backpanel for the MCR USB card reader to replace its dull green/red LEDs. The design calls for a regular WS2812B/SK6812/neopixel LED strip, which measures 16cm in length and contains 10 LEDs per unit, spaced at 60 LEDs per meter. Printing with an extrusion width of 0.5mm yields the best results. To secure the backlight module firmly in place, you can tap the holes for the alignment and mounting pins to create M4 threads, then use two 10mm M4 screws. Alternatively, you can glue an optional cable box with screw terminals directly into position. For optimal appearance, this design requires the use of matt, frosted, milky, or natural filament. I printed it using Reprapper's natural PLA (which I had purchased back in 2013).
