Spinning Top, easy to print, works great

thingiverse

This Spinning Top works great and is easy to print. A steel ball with 4.5 mm diameter is needed, but you can also print a tip (included), if you don't have such a steel ball. Many Spinning Tops can be found here, but I thought I could design a better one as I have found here so far. Most of the mass is at the circumference of the disc. It is really easy to print without any support or brim. My prototype spins 1:30 min. Update 1: Added small brim to the pin to prevent problems with warping ends I have had. Update 2: The axis is now hexagonal and conical. Update 3: The axis is now printed standing, with integrated brim. Update 4: The axis is now 5-cornered.
