Hi, Sir I am an electronic engineer from Pakistan. And I have personal interest and experience in 3d printing. Let me explain you. There are 2 ways to do it .The First way is we develop a 3d model, by looking at the original piece, or in other words we can replicate it, for this, I will need the material in front of me, Its the best way, when we will have the model in front of us, so if you can ship that to us, it would be best. Or If not, then send us proper pictures(because the picture you uploaded is very blurred image) and other things(its dimensions , length, width etc) that I will ask you if you hire me. The last way is I will ask you to send some proper pictures of the product from many angles, and a software will directly convert the photos into a model itself.
Don't get confused, it was just for your info, you only have to ship your desired wheel to us, and if you can't, then tell us and we will work on other available options :) The 3d printed model will be shipped back to you in less than a month. The delivery time is other than that.
