About this 3D model

A really fun, easy-to-print toy that entertains cats and kids alike. It rolls coins fast and straight and they zip right across the floor or table. I modeled this after a Brachistochrone Curve for really fast descent down a ramp. Works with most common coins, I've specifically tested it with the following: Canadian: Nickel Quarter Toonie ($2 coin) Euro: 1 cent 2 cent 1 EUR 2 EUR American: Half-dollar (50c) The best coin I tested was the 2 EUR coin, because it has nice weight and the thickness keeps it completely stable as it launches out the bottom. The American Half-dollar is also really nice because it's large and heavy and will roll a fair distance. Prints great with no supports required and comes out super sturdy, all corners are reinforced. Will survive a good amount of drops and being thrown around.
