Store your golf balls or display them in a pyramid stack, the choice is yours.

The bottom has tapered holes to locate onto the previous layer

V1 prints the fastest but also uses the most filament

V2 has rounded holes instead of chambered ones and added pins/holes to stack empty racks, optimized height to stack better / lower overall

V2 tapered gives a different aesthetic and is slightly easier to pick from the sides.

V2 thin tapered is optimised to use less filament (180g vs 258g) then normal but the holes are not as deep so may be less stable when stacked high.
