I designed a holder for a 70mm EDF (impeller) and 80mm EDF
You will find 4 versions with different holders
The original holder was made of wood and after a hard landing is broken
I use this for a RC model from VQ, Sonex (Hornet)
My EDF: TP Plastic 70mm-14B-EDF
Print best on the head, see picture
The author marked this model as their own original creation. Imported from Thingiverse.
