5CB is a common nematic liquid crystal. I printed this decoration for a friend working in the field. The channels are quite wide in order to accommodate the EL tubes. Due to purely vertical orientation, a lot of lateral scanlines appear. The shape made it really difficult to sand the details. I applied matte acrylic polish and UV coat by microfiber cloth (so that it looks icy) The electronics are contained at the base, which is the top of an İkea box,. I made a magnetic latch using 1 euro cent, and a neodymium 1mm button magnet for accessing the batteries.
