Simple knurling on Tinkercad (instructions in description)

Here's the way I do it. Whether it's the right way or not, it works for me. I'm not the best with Tinkercad but I can make a few things here and there. Ignore the noise and bad video quality as I'm not a professional YouTube either.

I'll just take a block and place it on the build plate. Shrink it down to about 1-2 mm in hight. Copy that block and rotate it 7°. Then just keep copying it until it forms the circle. Select all of those and group them together. Now copy that and raise it up to sit right on top of the first and rotate it 3°. Now group both of those together. Now copy that and place it on top of the first one. Keep copying until you get to the desired height of what you need. When all said and done, group everything together. You can adjust the size of to what you need after your done grouping. You can also adjust the number of degrees when making it to making it a more course knurling if need be.
