DJI Phantom 3 Landing Gear Extensions (3 different styles)

thingiverse

While creating our payload drop hook (thing 1259564) for our DJI Phantom 3 quad copter, we discovered that we required landing gear extensions to provide clearance for the folded-up drop hook. We did not want to reinvent the wheel, so we chose Tanemahuta's "Phantom 3 Gimbal Guard to go" (thing 909566) design as our mounting base on which to install our landing gear extensions. Many thanks are owed to Tanemahuta for his design. So, in order to utilize our Phantom 3 landing extensions, the following items will be needed: 2 - H5 labs landing gear extensions (this design) 1 - http://www.thingiverse.com/thing:909566 (P3 Gimbal Guard to go) 4 - 4-40 x 1/2" long screws 4 - 4-40 nuts Please consult the print settings for information on what worked best for us in printing the landing gear extensions. To assemble: Press fit the landing gear extensions onto the P3 Gimbal Guard to go. Align them so that they fit centered over the two beams that run next to and parallel to the original Phantom 3 landing gear bars (these run front-to-back). Refer to attached photos for details. Once aligned, use a 7/64" drill bit to drill the four holes in the P3 Gimbal Guard to go - use the holes in the landing gear extensions as guides for drilling (refer to attached photo to see how we drilled these holes using this method). Then, insert the 4-40 nuts into the indentations on the bottom of the landing gear extension arms. Finally, insert the 4-40 x 1/2" long screws so that they first pass through the holes drilled in the P3 Gimbal to go and then into the landing gear extensions (it's a good idea to use a small dab of removable loc-tite on the screw threads). Refer to the attached picture showing the completed assembly. When ready, simply attach the modified P3 Gimbal to go to your Phantom 3 and you're good to go. UPDATE (2/8/2016): Two new styles have been added. Style 2 moves the landing gear legs to be inline with original lading pads. Style 3 is based on style 2 and a bit more radical in that it twists the landing gear legs 45 degrees out, which should keep it completely out of the camera's view. I have not attempted to print either of these new designs yet. Feedback from anyone who tries to print and use these would be greatly appreciated as it may be awhile before I get to them (a strong gust of wind took out my Phantom 3, so I've a good many repairs to make). Best of luck to all.
