AK74U bolt / charging handle knob

In progress: Im trying to make a knurled handle which snaps on a cyma ak74 charging handle

How i made this:

I used image to stl converter by taking 2 pics of the stock handle shape. one profile i made into a negative to create a 3D 'scan'. of course scaled to actual size and increased by 1.05 so it actually fit.

I included the bolt handle I "scanned" if anyone wants to give it a go. the file I made was a quick demo if it actually fit on the handle (which it did) not perfectly straight,
