Pentagon lamp printed using PLA. The metal pendant fixture can be found at home depot and use any kind of bulb you want.
Printing Settings: 240 degrees nozzle temp and 72 bed temp. No need supports. To get the gray border just cut the white PLA at any stage you want and replace the PLA the gray one, or any other color. It took me almost 3 days to print in a CR10s5. The scale I used was for a printer capability of 500mmx 500mmx500mm but could be downsized as needed.
