Wonderful design, thanks for sharing file on thingiverse. Printed on Ender 5 in Flashforge grey PLA wich is slightly translucent. With a normal cheap white LED chain the PLA gets a soft blue glow. On my second make I merged all top part into one piece and all bottom parts into one piece in cura., saving me some assembly time and removing the need for support, as the "pyramids" support themselves.
Original walls need support, but if you form pyramids by adding all top or bottom wallsto the slicer, you no longer need support
