I did not like any of the parametric golf balls I was able to find, so I designed my own. This uses the fibonacci lattice to distribute points on the surface of a sphere in a relatively even way.

The included STL has a diameter of 42.7mm, dimple diameter of 3.5mm, and dimple depth of 0.18mm. 360 dimples fit with these parameters and no overlap.

Render time using OpenSCAD's stable build on my 5900x is 55 minutes at the stock settings.  Because of this, you should download a recent OpenSCAD nightly build and enable the fast-csg-safer and manifold features (minimum).  This takes the render time from 55 minutes down to 13 seconds.

Update 2/15/22 - Added a lower-poly (but smoother) version using the excellent geodesic_sphere from https://www.thingiverse.com/thing:1484333 

Update 12/18/24 - Added note to description recommending OpenSCAD nightly builds and speedup features.  The original author of geodesic sphere has copied their work here on printables, you can find the library here now: https://www.printables.com/model/163228-geodesic-sphere-for-openscad
