Mini 250 octocopter with 6 inch ducts

thingiverse

This is the 250 size ducted octocopter I built for the hobbyking beer lift. unfortunately I didn't have as big motors lying around as some of the entrants and my scales werent visible after compressing the video. It is printed in bridge nylon with zero infill. The booms are 16mm carbon tube the rest I used PLA but you can use whatever you like. I think they are all 25-35mm bolts used and some m3 threaded brass knurls melted into the PLA. I am dismantling it for parts now so I thought maybe someone else would like to have a go at printing one. Print Settings Rafts: No Supports: No Resolution: .2mm layers Infill: zero Notes: Print the nylon ducts with zero infill 4 top and bottom layers using .2mm layer height and .4mm nozzle. the PLA you can print however you like for the best strength Post-Printing
