Welcome, Luis! As a fellow finger top fancier, I also find repurposed tops a lot of fun. Especially liked the 1st one you showed.
My LEGO finger tops are sort of repurposed in that a top-making LEGO set has never been sold. But tens of thousands of distinct LEGO parts have been produced over the years, and the top designs you can make from them are seemingly endless
The same is surely true of all the parts salvageable from real-life gizmos.Looking forward to seeing what you come up with next.
