I made this cone since I didn't feel like buying some from a store. The original intent was for physical therapy, so I made it shorter and with a wide base so it wouldn't tip over. But you can use it for anything else.
Scale it however you'd like. Print it out of TPU, PLA, whatever suits your purpose. By default, it's 150mm (almost 6 inches) on a side and 120mm (about 4 ¾ inches) tall.
The author marked this model as their own original creation.
