I hollowed out the top bar blank so that the LEDs could shine through the top insert. With this pattern, you can make different inserts to go in the top if you don't like the flames - it has a base of 115mmx5mmx2mm. Use a white, opaque, or translucent filament to allow the LEDs to shine through the insert. it should be a tight fit, but a small amount of glue could hold it in place. a plexiglass or plastic insert that was laser cut could also be used and make for some very detailed additions to the blank.
The author remixed this model.
