Stool made with an empty spool

Edit: updated in italic a pair of details for better understanding about what I did.

With a lot of empty spools at home, I've found a use for one of them: as a stool for my daughter.
It is sized for a @fillamentum 750g spool, and you will need 3 legs with outer Ø22mm and 2mm thickness for the caps. Mine are made of Ø22 PVC pipe.
The printed triangles are fixed with small screws.
