Tired of spending all that time assembling tops that print in multiple pieces? Now your days of toil are over! This top prints upside-down as a single piece. It also has a hollow core, giving it a large rotational inertia to mass ratio, so it spins like a champ!

Instructions

Printed in PLA, 20% infill, 0.2mm layers. I printed this on a printer with a bed that moves in X and Y and it still printed up nicely, although if your printer's bed moves in X or Y (like mine) you'll probably want to print at a lower speed. After printing, just break off the support ring from the stem and give 'er a spin!
