Omkar Yantra LED wall light
This wall light consists of two pieces that are glued together with an LED lighting module inserted in between (see instructions for details). It hangs on a standard picture hanger. The sacred syllable 'OM" is in raised lettering in Devanagari script. In the example, I've inserted a filament change (M600 if the firmware supports it - it's an experimental feature in Marlin) at 1.7mm on the top piece to print the OM in gold filament.
The LED lighting modules consume very little power and need a 12 volt DC power source. You'll need cyanoacrylate (superglue) to glue the pieces together, or a hot-melt glue gun.
Blender sources are included at an early stage (before the font object is converted to a mesh) as well as in the final stage.
Credit for the Omkar glyph from the Sanskrit 2003 font goes to the Omkarananda Ashram.
