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.
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.
Now the customizer can produce ball cut into 8 pieces, so it can be printed with small printers and it has no extreme overhang area.
