LED 18

This is just a simple LED sign that should theoretically light up the 1 and the 8 if printed with transparent filament. Also 18_8_LED and 18_1_LED shall be printed with transparent filament. Print 18_8, 18_1, 18_8_LED and 18_1_LED so that the slope is facing up for best results.
Everything else should be non-transparent.

To light it up, insert a micro usb breakout board and 2 LED's in series. (the LED's have to be filed down to a length of 5mm from the top the beginning of the leads so that the light is no longer bundled and can spread out. Also cut the leads so it fits just right into the groove)
Should be pretty straight forward.

Have fun.
