Custom Elements

How do i download or create custom elements?

can you give an example? are you talking about tick marks, backgrounds, watch hands?

All of them. I figured out tge background image. I would like to figure out the rest of stuff like digital number, analog hands, tic marks, etc.

For digital numbers, just you text and your own fonts. For hands, hit the plus sign to import your own image, tick marks can somewhat be created using the built in ones with some work and masks.

Beyond that, there is an extensive resource section on the forum that other users have used to upload their own work:
