A topology-based hollow ball, with a print time of 1.5 hours. Pause halfway through the print, insert a vibrating LED flashing light (available on Taobao or Pinduoduo for around one yuan), and then finish printing. It's ready for playtime with your pet!

I used PLA material; my settings worked perfectly. If using other materials, you may need to adjust the printer’s overhang speed and variable layer height and speed.
