Added a Solid 33mm sphere in the center of the version with Heavy Duty interior support. Printed at 87%infill to make it weigh 45.5g (very very close to perfect golf ball weight)、 and printed with PETG filament. I have to say I am ASTONISHED at how well This ball works.
I'll try to get some good videos and upload the make. I feel like it's one of the best practice balls I have ever used、 and it has withstood some pretty hard slams into concrete so far.

I have not yet been able to test it with a full swing and a driver、 but I will definitely update when I do!

I also intend to try a version where I pause the print and fill the interior with hot glue to make a rubbery core like a real golf ball has.

Very excited!

What if you print it hollow, pause the print a few times and pour metal inside.

You mean like ball bearings? Injecting rubber might be interesting too.
However, whatever you do, it will be hard to make it balanced.

please make a version with a flat bottom. my printer is HORRIBLE at round stuff. thanks.

I found it prints best with my printers standard support option、 .and not the model with the 8 added supports

When I originally drew this, the standard software did a really poor job of adding supports and the result was really difficult to remove without leaving more scaring than my supports. Things have improved, but sometimes the supports are still difficult to remove.

Having said that, I've found you're right, a lot of parts with built in supports work better with software generated supports instead. With this part, you've got the option at least of deciding yourself.

Also, when I drew this, I was worried about the result being balanced, and a lot of the software generated infill is not symmetrical enough to be balanced. I see the people making dice have worried and played with this a lot as well.

Giving it a flat bottom would defeat the purpose of this model.
My printer is horrible at printing round stuff too, that's why I made the support structure which mostly works.

going golfing today going to see how a PLA ball holds up

This is the roundest thing I have ever printed. Kudos on the simple, yet effective support structures. Work well to putt with, haven't tried driving it.

maybe if you printed two halves then went back and filled the middle with a product like ninja flex mimicking the structure of a real golf ball

if possible print with nylon, might make it handle impact a little better

The ABS handled the impact fine. It's the deformation without internal support that was a problem. With internal support, it seems to survive.

Does this have the same amount of dimples as a normal golf ball?

There is no standard number of dimples or standard pattern of dimples on a golf ball. Every manufacturer does it a bit different.

This ball is not standard weight for a golf ball, however.

Now that would be interesting to see if it is possible to make a few more layers, like for a real golf ball. Leave a hole and fill the ball with rubber, or pause the bot and insert a smaller core. Something like this.
