How do I make something like this?

scanning is not a good option. Unless you know someone with an industrial scanner who will do it for you.

Generally much quicker and easier and more accurate to use digital calipers to measuure it.
Something like that handle is fairly easy to make in openscad.
Probably fairly easy in tinkercad too.

Make it from flexible pla.

Now all that said.
It's 'easy' if you know how to measure something with digital calipers AND know how to use a cad program of some kind.

So you have 2 options.
1) learn how to make things yourself.
2) pay someone to make it for you.

Thanks for the information. Its really amazing. You have to learn from other to pay the money.
You need to use cad program to use this type of design.

Thanks & Regards,
