You can copy the Saved Model and the Training Recipe to a new project by selecting the Saved Model and click on "Copy" at the bottom of the right panel. You will then get prompted with a few parameters regarding the target (current vs. new vs. existing project, keep all versions, etc.) before finally performing the copy and being redirected to the new Flow items created.
Not that you will need to share or copy the initial training Dataset along with it.
Since managing multiple projects for the same use-case can often add overhead, another alternative would be to keep your current Project structure but with a rearrangement of the Flow items using Flow zones. Experience has shown that this feature greatly helps users reach a better readability in their Flows.
Hope this helps!
