yeah the thin blades had to be treated well this is the reason i took them out of the fan casing for printing. it cost £100 just under 5inches from nose to rear. i used 3dcreationlabs really great service.
Frenchy Pilou: yes reality i used to work in a product design studio and we had several types of rapid prototyping machines so im lucky to have seen more than one of my designs come to life. this hover speeder is the first one to come out of my own pocket though so its more special :)
