1:1 scale customizable bowling ball

It's real scale printable bowling ball model. I made this in order to practice bowling at home while not breaking anything. It maybe too light to play a full stroke, but I think it's good enough to check my form and steps. Technically speaking, you can still get a full-15-pound of real bowling ball made of PLA! Just print it with 100% infill.

It's customizable. The terminologies that I used maybe different from what drillers use, but you'll have no problem with measuring your own ball and create a copy of it.

The online customizer produces only a poor quality model. If you want a perfect sphere ball, download the `bowling_ball.scad` file and try adjusting `$fa`. Lower the value smoother the model will be. `2` or `3` will be sufficient. I had to keep the value high cause the customizer hangs forever with lower values.

I'm still printing it now. I'll upload pictures when it done.

#Edit
Now the customizer can produce ball cut into 8 pieces, so it can be printed with small
