I am selling a 3d printed parabolic range extender that is roughly 80% of the way done. Unfortunately I ran out of filament when printing this one. I am selling the blue one in the picture (the white one is there for reference). It has copper foil tape. This greatly increases the range of your phantom 3 remote. I re-printed it with enough filament so I have a nice white one now that I use for myself. I don't need the partially printed one anymore so it's going for sale here. This one is a bit raw as I simply put the copper foil tape and used it. It can use some sanding, etc. to clean it up. Price is only $5 shipped anywhere in the USA. Brand new, these go for around 30 euros shipped.
