EDF stand for aerodynamic levitation
using a 50mm FMS EDF

you can see it on my video:

the EDF I used is
[25,76€ 29% OFF]FMS 50mm 11 Blades Ventilatore canalizzato EDF con 2627 KV4500 KV5400 3S 4S motore senza spazzola Parti RC from Giocattoli Hobby e robot on banggood https://banggood.app.link/oTaTUvVe7cb

but any EDF measure is ok, just scale it to the external diameter of your EDF

glue the stand legs with hot glie to the tube base and between them to increase stability
